A simulated image of NASA’s Nancy Grace Roman Space Telescope’s future observations toward the center of our galaxy, spanning less than 1 percent of the total area of Roman’s Galactic Bulge Time-Domain Survey. The simulated stars were drawn from the Besançon Galactic Model.

Exploring the Changing Universe with the Roman Space Telescope

The view from your backyard might paint the universe as an unchanging realm, where only twinkling stars and nearby objects, like satellites and meteors, stray from the apparent constancy. But stargazing through NASA’s upcoming Nancy Grace Roman Space Telescope will offer a front row seat to a dazzling display of cosmic fireworks sparkling across the sky.

Roman will view extremely faint infrared light, which has longer wavelengths than our eyes can see. Two of the mission’s core observing programs will monitor specific patches of the sky. Stitching the results together like stop-motion animation will create movies that reveal changing objects and fleeting events that would otherwise be hidden from our view.

This type of science, called time-domain astronomy, is difficult for telescopes that have smaller views of space. Roman’s large field of view will help us see huge swaths of the universe. Instead of always looking at specific things and events astronomers have already identified, Roman will be able to repeatedly observe large areas of the sky to catch phenomena scientists can't predict. Then astronomers can find things no one knew were there!

One of Roman’s main surveys, the Galactic Bulge Time-Domain Survey, will monitor hundreds of millions of stars toward the center of our Milky Way galaxy. Astronomers will see many of the stars appear to flash or flicker over time.

This animation illustrates the concept of gravitational microlensing. When one star in the sky appears to pass nearly in front of another, the light rays of the background source star are bent due to the warped space-time around the foreground star. The closer star is then a virtual magnifying glass, amplifying the brightness of the background source star, so we refer to the foreground star as the lens star. If the lens star harbors a planetary system, then those planets can also act as lenses, each one producing a short change in the brightness of the source. Thus, we discover the presence of each exoplanet, and measure its mass and how far it is from its star. Credit: NASA's Goddard Space Flight Center Conceptual Image Lab 

That can happen when something like a star or planet moves in front of a background star from our point of view. Because anything with mass warps the fabric of space-time, light from the distant star bends around the nearer object as it passes by. That makes the nearer object act as a natural magnifying glass, creating a temporary spike in the brightness of the background star’s light. That signal lets astronomers know there’s an intervening object, even if they can’t see it directly.

This artist’s concept shows the region of the Milky Way NASA’s Nancy Grace Roman Space Telescope’s Galactic Bulge Time-Domain Survey will cover – relatively uncharted territory when it comes to planet-finding. That’s important because the way planets form and evolve may be different depending on where in the galaxy they’re located. Our solar system is situated near the outskirts of the Milky Way, about halfway out on one of the galaxy’s spiral arms. A recent Kepler Space Telescope study showed that stars on the fringes of the Milky Way possess fewer of the most common planet types that have been detected so far. Roman will search in the opposite direction, toward the center of the galaxy, and could find differences in that galactic neighborhood, too.

Using this method, called microlensing, Roman will likely set a new record for the farthest-known exoplanet. That would offer a glimpse of a different galactic neighborhood that could be home to worlds quite unlike the more than 5,500 that are currently known. Roman’s microlensing observations will also find starless planets, black holes, neutron stars, and more!

This animation shows a planet crossing in front of, or transiting, its host star and the corresponding light curve astronomers would see. Using this technique, scientists anticipate NASA’s Nancy Grace Roman Space Telescope could find 100,000 new worlds. Credit: NASA’s Goddard Space Flight Center/Chris Smith (USRA/GESTAR)

Stars Roman sees may also appear to flicker when a planet crosses in front of, or transits, its host star as it orbits. Roman could find 100,000 planets this way! Small icy objects that haunt the outskirts of our own solar system, known as Kuiper belt objects, may occasionally pass in front of faraway stars Roman sees, too. Astronomers will be able to see how much water the Kuiper belt objects have because the ice absorbs specific wavelengths of infrared light, providing a “fingerprint” of its presence. This will give us a window into our solar system’s early days.

This animation visualizes a type Ia supernova.

Roman’s High Latitude Time-Domain Survey will look beyond our galaxy to hunt for type Ia supernovas. These exploding stars originate from some binary star systems that contain at least one white dwarf – the small, hot core remnant of a Sun-like star. In some cases, the dwarf may siphon material from its companion. This triggers a runaway reaction that ultimately detonates the thief once it reaches a specific point where it has gained so much mass that it becomes unstable.

NASA’s upcoming Nancy Grace Roman Space Telescope will see thousands of exploding stars called supernovae across vast stretches of time and space. Using these observations, astronomers aim to shine a light on several cosmic mysteries, providing a window onto the universe’s distant past. Credit: NASA’s Goddard Space Flight Center

Since these rare explosions each peak at a similar, known intrinsic brightness, astronomers can use them to determine how far away they are by simply measuring how bright they appear. Astronomers will use Roman to study the light of these supernovas to find out how quickly they appear to be moving away from us.

By comparing how fast they’re receding at different distances, scientists can trace cosmic expansion over time. This will help us understand whether and how dark energy – the unexplained pressure thought to speed up the universe’s expansion – has changed throughout the history of the universe.

NASA’s Nancy Grace Roman Space Telescope will survey the same areas of the sky every few days. Researchers will mine this data to identify kilonovas – explosions that happen when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.

And since this survey will repeatedly observe the same large vista of space, scientists will also see sporadic events like neutron stars colliding and stars being swept into black holes. Roman could even find new types of objects and events that astronomers have never seen before!

The Deep Webb

A YTP of NASA's 2022 live presentation showcasing the first images taken from the James Webb Space Telescope.

This monumental feat of human discovery was presented to the world in the form of a scuffed livestream where technical errors abound and production repeatedly failed to think on their feet to remedy issues as they came up. Peppered with some charmingly awkward/out-of-touch performances by the various presenters, most of which are astronomers and engineers whom I have the deepest respect for despite it all.

I watched this event as it was broadcast and immediately knew it would make for an excellent YTP source. I was so very correct, and my biggest regret was sitting on it for two years rather than working with it immediately.

❝ sky full of stars, j. burrow. ❞  ‎ ‎ ┉  

‎ ‎ ⁎⠀┉⠀summary: joe's a big space nerd. you're a big space nerd. it's a match made in space nerd heaven.

‎ ‎ ⁎⠀┉⠀author's note: literally laid awake last night thinking about this. decided to write it during my lecture. short and sweet but i love writing joe in love. suppressing the urge to cite my sources on this lol. ty to wikipedia's black holes article <3 also don't worry y'all will still get a game day fic on sunday 🙂‍↕️

‎ ‎ ⁎⠀┉⠀warnings: science talk, general cheesiness.

‎ ‎ ⁎⠀┉⠀pairing: joe burrow x nasa engineer!reader.

‎ ‎ ⁎⠀┉⠀word count: 1k.

Your eyes scanned the living room, your gaze lingering on the framed LSU jersey hanging on the wall. A soft chuckle escaped your lips as you thought of Joe's insistence on displaying his pride so prominently in his Cincinnati home. Despite his celebrity status, he remained as down-to-earth as the day the two of you met eight months ago, a quality you cherished deeply.

The gentle hum of the air conditioner filled the quiet room as the documentary's narrator droned on about black holes. Joe's breathing grew even and steady, his head comfortably nestled in your lap. You felt his hand twitch in his half-sleep, his thumb brushing against your thigh through the fabric of your shorts. You gently stroked his hair, a soft smile playing on your lips.

Your thoughts drifted to the upcoming mission you were helping to prepare at the Johnson Space Center. The excitement of possibly making more discoveries on your Mars probe was palpable, and you couldn't wait to get back to Houston. Yet, here you were, feeling more content than ever, with a man you never thought you’d end up with. The rhythmic beat of Joe's heart against your palm was a reminder of the love the two of you had found amidst your two dramatically different lives.

You leaned back, your hand still cradling Joe's head, and refocused on the documentary. The TV screen flickered with images of stars, galaxies, and cosmic phenomena that you knew so well from your work, yet seeing them here, in Joe's home, made them feel so much more profound.

“So, how do black holes, like, eat stars?” Joe’s sleepy voice interrupted the silence. His eyes remained closed, but his mind was clearly still processing the information he had been hearing.

“It’s not so much that they eat stars, but rather they have such intense gravitational pull that nothing can escape them, not even light,” You explained, your voice a soothing murmur. You felt Joe’s head shift slightly, his curiosity piqued.

“So, it’s like a cosmic vacuum cleaner?” He mumbled, a hint of a smile in his voice.

You laughed, the sound echoing lightly in the room. “In a way, yes. But a vacuum cleaner you definitely don’t want to get too close to. Once something enters a black hole, it’s gone forever.”

Joe’s eyes fluttered open, and he looked up at you, the corners of his mouth tugging into a smile. “How can something be that powerful?” His gaze was earnest, the curiosity in his eyes warming your heart.

“It’s all about the mass and gravity. When a star dies and collapses, it can become so dense that its gravity is just too much for anything to resist. Not even light can escape, which is why we call them black holes. They’re like the universe’s trapdoor.” Your voice was soft, your eyes shining with the same enthusiasm that had captured Joe’s attention when you’d first described your job to him.

Joe nodded, his eyes drifting back to the TV screen. His fingers twined with yours, and you felt a gentle squeeze. “And what happens when something does fall in?” His question was genuine, his curiosity a bridge between your worlds.

“Well, we think that anything that gets too close gets stretched out like spaghetti. But before that, it passes the point of no return, gravity gets so intense that it bends time and space itself. It’s like nothing we can truly imagine.” Your words painted a vivid picture in the quiet room, your voice a mix of wonder and knowledge.

“You’re like nothing I could truly imagine. You’re like my own black hole, pulling me in with your brilliance every day.” Joe’s words were a gentle whisper, his blue eyes opening to find yours, a warmth that didn’t quite match the cosmic chaos on the screen.

Your heart fluttered. “You’re not so bad yourself, Mr. Heisman.” You leaned down to kiss his forehead, your smile tender. The room felt smaller, the universe’s mysteries forgotten as the two of your shared a moment of quiet intimacy.

The documentary played on, but your attention had shifted. Joe’s hand found yours again, fingers interlocking. He pulled himself up, dirty blonde hair messy from rest, eyes squinting in the light. “You know I’m going to keep asking questions until I understand everything you do, right?”

“I wouldn’t have it any other way, Joey. You know I love talking about this stuff with you.” Your voice was filled with affection as you reached for the remote and paused the documentary. The room was bathed in the soft glow of the TV, the only light source in the otherwise darkened space.

Joe sat up, his hand still holding yours. He leaned in, your eyes locking for a brief moment before your lips met in a gentle kiss that grew in passion. His arms wrapped around you, pulling you closer as you shifted on the couch to face him. Your kisses grew deeper, a silent declaration of your love and appreciation for one another’s differences and shared moments of wonder.

As you pulled apart, Joe whispered, “You know, I still can’t believe you agreed to go out with me. A guy who throws a football for a living asking out a NASA engineer.” His self-deprecation made you laugh again, the sound music to his ears. “Still not sure why you’re with me.”

“Why not?” you said, your voice filled with warmth. “You’re smarter than you give yourself credit for, Joe. And you’re incredibly good at what you do. Maybe not launching rockets, but you have your own kind of rocket science going on out there on the field.”

Joe chuckled, the sound rumbling through his chest and into yours. “You always know what to say to boost my ego.”

“I’ll say whatever it takes to get me ahead of Ja’Marr in your heart,” you teased with a laugh, leaning forward to steal another kiss from his pink lips. The warmth of his breath tickled your skin, sending a shiver down your spine.

Joe’s arms tightened around you, his eyes lighting up with mischief. “I don’t know, he’s pretty good at catching my throws.”

“Well, I’m pretty good at catching your heart, so I think we’re even,” you quipped back, your eyes sparkling with love and amusement.

Joe’s chuckle grew louder, the sound rumbling through the room like thunder. He leaned back, pulling you with him until you were lying on top of him, your legs draped over his. “You definitely win that title, babe. No contest.”

Your smile never left your face as you looked down at him. His strong arms wrapped around your waist, holding you in place. You felt his heartbeat beneath you, a steady drum that matched the rhythm of your own. The air between the two of you was electric, the kind of charge that could spark a star into existence.

IN EVENT OF MOON DISASTER - speech written by Bill Saffire for the Apollo XI space flight, in the event the astronauts were stranded on the Moon and could not return to Earth. (source)

Transcript under the cut

To : H. R. Halderman

From: Bill Safire

July 18, 1969

IN EVENT OF MOON DISASTER:

Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace. These brave men, Neil Armstrong and Edwin Aldrin, know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice. These two men are laying down their lives in mankind's most noble goal: the search for truth and understanding. They will be mourned by their families and friends; they will be mourned by their nation; they will be mourned by the people of the world; they will be mourned by a Mother Earth that dared send two of her sons into the unknown. In their exploration, they stirred the people of the world to fees as one; in their sacrifice, they bin more tightly the brotherhood of man. In ancient day, men looked at stars and saw their heroes in the constellations. In modern times, we do much the same, but our heroes are epic men of flesh and blood. Others will follow, and surely find their way home. Man's search will not be denied. But these men were the first, and they will remain the foremost in our hearts. For every human being who looks up at the moon in the nights to come will know that there is some corner of another world that is forever mankind.

PRIOR TO THE PRESIDENT'S STATEMENT:

The President should telephone each of the widows-to-be.

AFTER THE PRESIDENT'S STATEMENT, AT THE POINT WHEN NASA ENDS COMMUNICATIONS WITH THE MEN:

A clergyman should adopt the same procedure as a burial at sea, commending their souls to "the deepest of the deep" concluding with the Lord's Prayer.

NGC 602: Stars Versus Pillars from Webb Credit: ESA/Webb, NASA & CSA, P. Zeidler, E. Sabbi, A. Nota, M. Zamani (ESA/Webb)

Explanation: The stars are destroying the pillars. More specifically, some of the newly formed stars in the image center are emitting light so energetic that is evaporating the gas and dust in the surrounding pillars. Simultaneously, the pillars themselves are still trying to form new stars. The whole setting is the star cluster NGC 602, and this new vista was taken by the Webb Space Telescope in multiple infrared colors. In comparison, a roll-over image shows the same star cluster in visible light, taken previously by the Hubble Space Telescope. NGC 602 is located near the perimeter of the Small Magellanic Cloud (SMC), a small satellite galaxy of our Milky Way galaxy. At the estimated distance of the SMC, the featured picture spans about 200 light-years. A tantalizing assortment of background galaxies are also visible -- mostly around the edges -- that are at least hundreds of millions of light-years beyond.

since we're all talking about eclipses let me share my favourite eclipse fact: the mystery eclipse of 811

eclipses were pretty noteworthy in the middle ages, as were all movements of the heavenly bodies - particularly for calculating the date of easter (which is determined by the lunar cycle, following the calculation of passover).

a list of eclipses can be found in a few manuscripts produced between 809 and 812 in the carolingian empire, and it's broadly accurate. the entries record the date and time of the eclipse, as well as its location in the sky, as for the eclipse of 807: "In 807, there was again an eclipse of the Sun on 11 February in the 26th part of Aquarius around the sixth hour of the day." (this is correct for the year 807, and was probably a record of a past event.)

however, one entry simply reads: "In 811, there was an eclipse of the Sun on 27 April, in the first hour of the day." NASA records show when historical eclipses occured, and there was no eclipse visible in Europe in the year 811. But there was an eclipse that year - in Australia (on the 26th of May).

So the list wasn't a record of observed eclipses, but a list of predictions - using the easter table and some very good maths, the author was able to calculate when future eclipses would occur, even in places where nobody from europe had ever been. the location wasn't included, because they knew that the constellations would look different in the southern hemisphere.

this all goes to show that medieval people weren't stupid - their understanding of the world may have been vastly different from our own, but they were just as curious as anybody else at any other point in time. dismissing the middle ages as a 'dark age' when knowledge was stunted by belief fails to see how wonderful the middle ages can be - how people have always been brilliant, and curious, and have sought out new knowledge, all through history.

(this info comes mainly from a blog post by the wonderful james t. palmer, which is here, and has some more source links. ive also heard about it in papers/wider reading but i cant give a source for those)

When will your state next be visited by a total solar eclipse?

by u/darwinpatrick

In preparation for next month's big event I put a map together of the next time each state will be in the path of totality. Data from here. Some things to note that I didn't include on the map:  

   - Oregon does get totality in 2108 but it's such a thin slice it barely shows up  

   - timeanddate.com and a couple other sources show more generous areas of totality at the beginning and end of each eclipse, likely due to them counting an eclipsed sun partially below the horizon as totality. The NASA shapefiles I used do not take this into account and thus my data is a bit more conservative. Checking, for example, the 2079 eclipse on timeanddate.com shows Delaware and Maryland making the cut whereas my map doesn't.

THE EUROPA CLIPPER LAUNCHED THIS MORNING, AND I AM SO NOT NORMAL ABOUT IT!!!!!

Space is so fucking awesome. We're headed to one of JUPITER'S MOONS!

Every time a launch happens, it makes the latent space enthusiast in the back of my brain jump up and down. It also derailed all my plans for today. I did have plans.

Instead, someone made one comment about how I could now maybe make mission patches on my embroidery machine, and the space thing crossed over with my current hyperfixation (silm) to produce THIS:

Mission patch for the launch of Gil-Estel! A bit messy, but a good place to start!

Design and linguistics details under the cut, because I put WAY too much thought into it and now must talk SOMEONE's ear off about it. Feel free to ignore this bit:

So, to start: Elvish NASA. I chose to call them Vardildi Elengolmo Vilciryamoyë, or VEV. The Followers of Varda, Astronomers and Astronauts. This could very much be totally wrong. Vardildi is Varda+the suffix used in Yavannildi, the followers of Yavanna. Elengolmo comes from the coined word for astronomer, Elengolmë (star-lore), with the -o suffix from nolmo, wise person. Vilciryamoyë takes the vil- from the root of vilya, meaning air, sky. ciryamo is mariner, and yë is the suffix added to the second word meaning 'and'. (I may be very, VERY wrong on this! If anyone has better ideas, I very much welcome input/guidance/constructive criticism)

So I stuck the tengwar for this on either side of the patch. (None of the tengwar is all that legible, though, I'm working on getting that sorted out) Most NASA mission patches don't actually have NASA on them, but I put it on anyway. Here is the tengwar and the start of a logo I made an attempt at (the tehta is supposed to be a shooting star, but that did NOT come through clearly in the embroidery [because it's tiny]):

(Probably going to try to make an elvish NASA patch before too long, honestly)

Most NASA patches (from research I did with great self-restraint here) have the (last) names of the astronauts. Not sure if they also have the name of the craft or if that's generally somewhere else, but I put both--Eärendil Ardamírë (his fathername and mothername) are the tengwar at the bottom of the patch, and Vingilotë is written on the keel of the ship. None of these are legible because they are small, and my machine has limits. It's a work in progress. Also I apologize for the bad lighting in the photo.

NASA patches sometimes also have a mission motto. That's the tengwar across the top of the patch here-- aiya Eärendil elenion ancalima, Hail Eärendil, brightest of stars (a common cry among elves and Frodo [when facing Shelob]).

(I half wanted to do something a bit more funny--maybe something like 'Now I have become Venus,' or 'Do I get to come down?' but this was a bit easier since it comes pre-translated into Quenya and tengwar, and also I have no faith in my Quenya translations that are any longer than a word)

The horizon is flat because Númenor exists, in the middle there between the shore of Middle-Earth and a teensy bit of Valinor and the Enchanted Isles.

The design for the Silmaril is sort of taken from the heraldic device Tolkien designed for the Silmarilli (though it isn't clear), and it is rayed with the six-pointed star from Eärendil's device. (I stuck the moon phases from the same source around the edges as well)

This was really fun, even if it might be the silliest thing I've ever made! It definitely needs some workshopping--i don't mind the black lines framing some sections from the background fabric, but I might try turning all the tengwar into lines of stitches instead-the satin columns really are illegible.

I now need to restrain myself from doing some sort of NASA/Astronaut Earendil AU, because it now sounds kind of fun (I do not have the background knowledge for this)

Hi, I love your works!! I was wondering where you find the original, unedited pictures you use for your art? Do you take them yourself or find them online?

Hey there! I get them from many different sources! Whenever I can I use my own, and sometimes my followers send me cool pics to use (or put them up in the Sacrificial Altar channel in my Discord), but I find most of what I use through public domain sources online!

For the online part, I put this little list together with some of the common resources I use! Feel free to share it around and copy it:

For an easier experience, I'll copy the relevant part below:

STOCK SITES

- Unsplash: Usually the best quality out of the free stock sites. They’ll try to sell you a subscription plan but you can ignore that.

- Adobe Stock: Select “Free” on the dropdown menu next to the search bar. The free image selection here is big and high-quality, though they feel more like stock pictures than natural photos. Note: They limit how many pictures you can download per account per day, but you can make several accounts to circumvent this if you use it a lot.

- Texturelabs: lots of free, very high-quality textures!

- Pexels: Similar to Unsplash, but it has more pictures with people. If you need a photo with models, this is usually the best place.

- Pixabay: Widest selection, but worst quality control. Go here if you haven’t found anything in other sites and don’t mind sifting through a bunch of garbage pics and occasional AI images.

PUBLIC DOMAIN SOURCES

- Wikimedia Commons: an enormous selection of CC and public domain pictures. Super useful, especially for the really specific images that you'd expect to find on a Wikipedia article. Always check the copyright conditions! To filter by license, search something and then click on the License dropdown under the search bar. Select “No restrictions” for public domain images.

- Picryl: A repository of public domain sources, ranging from ancient historical books and artifacts to fairly modern pictures. If you're looking for something old/historical, chances are it's here! This website is probably one of the most complicated ones to use, so here are three important tips before you use it:

This site added a paywall that appears after the 3rd page of search results. To remove it, install uBlock Origin, go to the “My Filters” page (clicking on the gear icon after opening the extension), and paste this filter: picryl.com##._9oJ0c2

After searching, use the timeline on the top right to narrow down the result by year.

It won’t let you download the full picture without paying, but it always has a link to the source site below the description. Click on that, then copy-paste the image’s name to find it in the original source. That way you can get it for free, and often in better quality than Picryl offers.

National Archives Catalog, The Library of Congress, NASA, and Europeana have wide selections, but they are included in Picryl so it’s usually better to search there and then download them in the source as mentioned above!

- Flickr Search: a ton of usable pictures with a generally more amateur feel, just remember to filter by license using the “Any license” dropdown menu. When you find an image, make sure to check its specific license (you can find it below the image, on the right side).

- Openverse: The official Creative Commons archive, has many sources! Includes other sites on this list, but has a lot of clutter if you don’t filter.

- iNaturalist: a repository of user-submitted images of animals, plants, and fungi. Look for a genus or species, then navigate to the photo list and filter by license.

MUSEUM COLLECTIONS

- The Met: An amazing selection of artifacts from all over the world, with top quality photographs of most of them (usually with several angles for each). You can filter images by material, location, and era.

- Getty Museum: Another smaller selection of museum pieces, but this one includes old photos as well as artifacts. You can also filter by dates, materials and cultures. Make sure you include the “Open Content” filter to only see public domain things!

- Smithsonian: Big selection of around 5 million museum pieces, with some 3D scans of museum pieces. Most pieces just have a single picture that can sometimes be low quality, but pieces with 3D models sometimes also include a lot of high quality photos from multiple angles. This collection also includes things from museums of natural history, so you can also use it to search for bones and specimens.

- Artvee: public domain classical art. They make you pay to download high-quality images.

If you guys got any others, please let me know and I'll add them to the collection!

Imagine being the loser ass tool, Yisha Raziel, who made a deepfake of Bella Hadid saying she supports Israel. 🤮

If you’re reading this, I am telling you right now, you better second and third guess what you see and hear on social media and the news. Stick to reliable news sources. Vet them. Require multiple, trusted sources. Validate links to sources. In the last several months, I’ve seen the deepfake of President Nixon talking about the failed NASA mission that never happened. I’ve seen a deepfake of Joe Biden hilariously using profanity to trash talk Trump - Biden’s deepfake, however, was made to be intentionally obvious that it wasn’t his words, or something he would actually say.

But imagine a viral deepfake video of Biden announcing a nuclear strike on Russia within the next 20 minutes? Or a deepfake of Biden reintroducing the draft to support Israel? Or a deepfake of Biden withdrawing from the 2024 election and endorsing Trump…

These kinds of things are going to begin happening a lot more, especially with the proliferation of troll farms, and especially since YouTube, Twitter (I refuse to call it X), and Facebook have all eviscerated their verification and factcheck teams that used to at least attempt to limit disinformation and misinformation.

Pay attention, peeps.

Don’t get bamboozled.

Nobody talks about how fucking cool Edgar and Eric Jomfru are and it's actually so sad.

These guys attended EVERY Dethklok show, with ZERO injuries, meaning they traveled the entire world. Not only that, they turned it into a business- They sold merch on their website, which had hundreds of thousands of daily views. That's fandom clout you can never even dream of.

They had the balls to stand there and threaten Dethklok for money. After Eric is shot, Edgar still has enough drive to somehow evade several snipers and be captured alive, plot his escape, swim out with a kid on his back, and become an international terrorist capable of literal mind control. He lived with a guy who spent his entire life in near-perfect solitude and they seemed to get along pretty well. Imagine their little domestic day to day life, between the revengence.

He escaped a horde of angry burn victims, once again alive, infiltrated Mordhaus (and lived AGAIN) to take the brute force route of shooting Dethklok with a gun (Magnus could never) and was still able to put his hatred aside when he realized this isn't what Eric wanted.

Despite everything Dethklok put Edgar Jomfru through he was able to put aside his hatred (and he still says they make him sick to his stomach, in DSR) and admit they meant something to him- to his brother, to a lot of people- and were part of a greater whole that he didn't have a right to destroy. Something he was ultimately willing to put personal grudges aside and die for.

He and his brother dropped out of HARVARD to follow a metal band on the road and by all we're shown, their only regret was being hit by a drunk driver. They still made what looks to be a pretty comfortable, possibly even rich (concert tickets ain't cheap for Dethklok) lifestyle for themselves.

Edgar is never once truly inhibited by his disability and never allows it to define him, and it ISNT the source of his rage, or the start of his character arc. Do you know how rare that is?

They start off as typical toxic fans who have made their livelihood by feeling entitled to someone else's work, only to end up with a deeper respect for them as people and for their output as real art with meaning to the world. They could've been NASA scientists or some other kind of mad genius, but instead, they followed their passion for metal and that's honestly badass? Also they're from Ohio so you know they're self starters because there's fuck all to do there.

They never lose their virginity because they never lose, period.

"On a blustery day in early March, the who’s who of methane research gathered at Vandenberg Space Force Base in Santa Barbara, California. Dozens of people crammed into a NASA mission control center. Others watched from cars pulled alongside roads just outside the sprawling facility. Many more followed a livestream. They came from across the country to witness the launch of an oven-sized satellite capable of detecting the potent planet-warming gas from space. 

The amount of methane, the primary component in natural gas, in the atmosphere has been rising steadily over the last few decades, reaching nearly three times as much as preindustrial times. About a third of methane emissions in the United States occur during the extraction of fossil fuels as the gas seeps from wellheads, pipelines, and other equipment. The rest come from agricultural operations, landfills, coal mining, and other sources. Some of these leaks are large enough to be seen from orbit. Others are miniscule, yet contribute to a growing problem.

Identifying and repairing them is a relatively straightforward climate solution. Methane has a warming potential about 80 times higher than carbon dioxide over a 20-year period, so reducing its levels in the atmosphere can help curb global temperature rise. And unlike other industries where the technology to decarbonize is still relatively new, oil and gas companies have long had the tools and know-how to fix these leaks.

MethaneSAT, the gas-detecting device launched in March, is the latest in a growing armada of satellites designed to detect methane. Led by the nonprofit Environmental Defense Fund, or EDF, and more than six years in the making, the satellite has the ability to circle the globe 15 times a day and monitor regions where 80 percent of the world’s oil and gas is produced. Along with other satellites in orbit, it is expected to dramatically change how regulators and watchdogs police the oil and gas industry...

A couple hours after the rocket blasted off, Wofsy, Hamburg, and his colleagues watched on a television at a hotel about two miles away as their creation was ejected into orbit. It was a jubilant moment for members of the team, many of whom had traveled to Vandenberg with their partners, parents, and children. “Everybody spontaneously broke into a cheer,” Wofsy said. “You [would’ve] thought that your team scored a touchdown during overtime.”

The data the satellite generates in the coming months will be publicly accessible — available for environmental advocates, oil and gas companies, and regulators alike. Each has an interest in the information MethaneSAT will beam home. Climate advocates hope to use it to push for more stringent regulations governing methane emissions and to hold negligent operators accountable. Fossil fuel companies, many of which do their own monitoring, could use the information to pinpoint and repair leaks, avoiding penalties and recouping a resource they can sell. Regulators could use the data to identify hotspots, develop targeted policies, and catch polluters. For the first time, the Environmental Protection Agency is taking steps to be able to use third-party data to enforce its air quality regulations, developing guidelines for using the intelligence satellites like MethaneSAT will provide. The satellite is so important to the agency’s efforts that EPA Administrator Michael Regan was in Santa Barbara for the launch as was a congressional lawmaker. Activists hailed the satellite as a much-needed tool to address climate change. 

“This is going to radically change the amount of empirically observed data that we have and vastly increase our understanding of the amount of methane emissions that are currently happening and what needs to be done to reduce them,” said Dakota Raynes, a research and policy manager at the environmental nonprofit Earthworks. “I’m hopeful that gaining that understanding is going to help continue to shift the narrative towards [the] phase down of fossil fuels.”

With the satellite safely orbiting 370 miles above the Earth’s surface, the mission enters a critical second phase. In the coming months, EDF researchers will calibrate equipment and ensure the satellite works as planned. By next year [2025], it is expected to transmit reams of information from around the world."

The photograph “Earthrise” was captured on Christmas Eve 1968 by astronaut Willam Anders aboard Apollo 8 — the first manned space mission to orbit the moon. Anders died on Friday at age 90 when a small plane he was piloting crashed near Roche Harbor, Washington. His famous photograph of Earth rising over the lunar landscape showed humans a perspective of our planet that we had never seen before and helped spark the modern environmental movement.

It also inspired our founder, Benjamin Grant, to begin Daily Overview in 2013 and to share the “Overview Effect” — the awe of seeing Earth from a great distance — with as many people as possible. We are forever grateful for Anders’ work, and remain inspired by it today.
