Okay so I fucking adore “Jason feels peace around Danny as the pit shuts the fuck up”

Now give me the slow burn

Just two lads trying to help but keeping it as not-weird as possible

Weekly coffee dates where Danny and Jason just… go somewhere

Read in the park

See a movie

Hang out behind a mall doing kick flips, whatever

Danny doesn’t wanna take advantage of the warm fuzzies Jason gets around him cuz they’re not personal, this is just…

A weirdly fast friendship speedrun

Someone who finally, fully gets him, and yeah, maybe just getting to be himself feels pretty fucking good to Danny too

Jason doesn’t want to impose any more than he surely already is, this is the Ghost King, taking time out of his schedule just to hang out with him so he can have some self control

He’s always and only a burden, Danny’s clearly just being cool cuz he’s the only King Jason’s met who actually fucking cares

He’d do the same for anyone

And so Jason tries to make sure they’re always doing something convenient/easy for Danny, something Danny likes to do

And Danny’s Physically Allergic to asking for anything or telling people things he wants or needs, so this requires Jason’s full detective abilities

And Tim’s but shut the fuck up no one will ever no Jason caved and asked for help

So when Jason sets up their next weekly sesh and takes Danny to the planetarium (maybe he was scared to ask first, maybe he was prepared to wimp out, it’s a surprise stfu)

And sees Danny’s whole face just light up

And they go inside, and Danny’s glowing in human form, bouncing from one place to another, gushing about everything

Jason knows he’s even gonna accept a favour from B to get the whole place to themselves for an overnight viewing

Cuz all he can feel isn’t just the soothing calm of the pit being silent, isn’t just the satisfaction of a job well done

He can feel the joy, the excitement, the radiant enthusiasm pouring off of Danny as if it were his own (and maybe something soft and small and fond that’s truly his)

And Danny

Danny’s a competitive little bitch

If we’re playing “Find Each Others’ Secret Hobbies” he’s got the god of software and his lesser subject Technus both on the line

(Technus stays Tucker’s subject instead of Danny’s until he can hack the PDA, it was a dare)

So he brings Jason out of Gotham for the first time (maybe through the zone, it’s fast travel either way) and they do Shakespeare in the Park

And Jason knows exactly what Danny’s doing (the bastard, this is supposed to be how Jason thanks him for this clearly super annoying favour) but he’s

He’s not had the chance to be soft in so long

To be the literature nerd he’s never left behind

It takes literal years for them to realize they’ve been competitively dating each other and everyone else is absolutely betting on when they will finally kiss

Danny moves in and Jason makes a joke about “well I guess we won’t need our weekly hang sesh” and Danny stares him dead in the eye, full Eldritch Horror

“Does that mean I win?”

So nah Date Night is permanent and eternal and every fucking rogue in Gotham knows to hold it sacred

seeing a lot of extremely positive moon and astronomy tags on my stuff and guess what

you can just do astronomy if you want. that is a thing you can do for free without any equipment or special education. i don't think enough people know this

see this website. it's a free sky simulator. it's available as an app for iOS/android, on the website itself, and on macOS/windows/linux.

whenever you want to go outside and look at the sky, take a look at stellarium and it'll tell you what you're seeing when you look up.

for instance this is roughly what you'll see if you're in the northern hemisphere around 7pm EST

it's all right there. you can just go outside and do it. for free

do astronomy

and reblog this for others if you already do astronomy or if this was a good/useful resource for yourself

There is a mysterious computer in one of the planetarium offices. When I found it, it was underneath a computer desk (normal). It did not have a plug (weird). It had a monitor on the computer desk and a keyboard (normal). They could not be plugged in to the computer (weird). It turns on, and I went looking for a monitor cable that would fit because the planetarium has a big bucket of monitor cables stored behind the dome. It seems to use some variation of a VGA cable; exact species could not be determined, and a cable that was the correct gender could not be found. (weird.) The computer seems to have been custom built and has a 2TB hard drive visible. I cannot discern its purpose.

My working theories are:

It ran the previous planetarium software prior to its current system.

It has something to do with the laser shows.

It's the backup drive for... something.

It has a label that says "PREFLIGHT"; this implies it was stolen off an aircraft somehow.

It's alien technology that, based on its bizarre assortment of ports, got punted out of an alternate reality.

Open to suggestions with how to deal with the thing.

Hey it's me again and I'm just wanting to ask a few last questions.

Can a Gas Giant be white while not being made of helium? I have this one GG I'm my k type system that's white but it's basically the Jupiter of the system in terms of distance.

Could two minor moons of 512 and 493 km respectively be enough to affect tides on a world that's about 10'000 km across and a bit over a quarter the mass of Earth?

How far can a body have a ring system?

Photo for the 2nd question for reference. I actually wonder if both moons would hypothetically be viewable in the sky and if this planet's system is stable. Anyways thanks if you reply! You been a big help.

1: sure. water vapor clouds are white. a gas giant in the habitable zone would be white due to the water vapor clouds, with blue skies. Also, a jovian gas giant which somehow had pure ammonia ice clouds with no other contaminants to make it brown could be white or gray. But I'm not sure what would cause that to happen. But if you just want it to be white then that's a possible explanation. Or maybe there's some kind of white smoky haze covering everything. Planets are weird and hobby worldbuilding doesn't have to get everything exactly right, it's just nice to be able to provide a basic explanation if it comes up, even if it won't hold up to further inspection.

2: as i understand it, tidal forces are related to angular size and density. so if the moon and the sun were the same density as eachother, their tidal effect on the earth would be the same (since their angular sizes are the same.) The Sun is about half the density of the moon, so half the tidal effect. So if the satellites are comparable in apparent size to the Earth's moon, they will have a comparable tidal effect. (Note that for things like tidal heating, the period and eccentricity will matter quite a lot as well)

Calculate angular size using the Cosine Approximation:

angular diameter in radians = distance to object / diameter of object.

(remember you'll probably want to convert from radians to degrees or arcminutes.)

3: the roche limit is the outermost limit of a planetary ring system. beyond that distance, debris will accrete into one or more satellites. To maximize this, maximize the ratio of the densities--a dense superjovian with icy fluff rings will have a proportionally much larger ring system than a saturnian planet with rocky/iron rings, for example. The innermost limit is typically the exosphere of the planet's atmosphere.

4: the moons look like they ought to be stable to me. Only way to test is to put it into something like Universe Sandbox^2 with the most stable integrator settings (actually nowadays i think the default integrator settings will work?) and run time forwards a bunch.

It goes without saying that asteroid moons of that size would be visible in the sky--probably much brighter than the planets appear in Earth's skies. But the question of whether they're visible as 'disks' (rather than point sources) comes down to their apparent size. It is technically possible to see the crescent shape of Venus, when it is close enough that its angular size is 0.018 degrees. But I haven't had such luck with that. The Moon is about 0.5 degrees in apparent diameter as seen from the Earth. Objects about 0.1 degrees in size should be apparent as circular (or blobby if they're irregular asteroids) objects in the sky. Smaller than that and it gets harder and harder to distinguish from a dot.

I would also consider getting Space Engine and making a mod config file for it to render your system. I've done that for non-Kerbal worldbuilding projects in the past and even if you dont go to the trouble of making custom maps for the objects, it's still a good way to visualize everything, and how big things should be. Celestia can also do this.

(Of course Kerbal Space Program is the best way to make a fictional solar system because, unlike planetarium software, your worldbuilding decisions become manifest as game design, and you can naturally get an idea of not just what the system should look like, but how it would work if a space program had to fly through it. It's absolutely the best way to make your solar system scale worldbuilding projects seem real. It is however a frustrating hobby to get into.)

someone in my department did a planetarium show over the weekend and sent me some pictures. for some reason I’m cracking up at, like, whoever designed this software finding it necessary to write “astronomy” in size 40 font

just in case you’re confused I guess!!!

[dahyeltal]

I did two fully scripted planetarium shows today featuring Queer Star Stories! I wrote the verbal script and the software script, and it was nearly flawless. I also got to nerd out about astronomy and mythos after both shows during audience choice/Q&A time, particularly the second show which was restricted to 18+. I’m so dang tired, but it was fun and I loved every second of it.

Astronomy school Lab Equipment Manufacturer, Suppliers and Exporter in India

Astronomy school science equipmentis a broad category that encompasses a wide range of tools and materials used to teach and learn about the universe. Some of the most common pieces of astronomy equipment include telescopes, binoculars, planetariums, globes, and star charts. These tools can be used to observe the night sky, study the constellations, and learn about the different objects in space. Telescopes are perhaps the most iconic piece of astronomy equipment. They allow us to magnify distant objects in the night sky, making it possible to see details that would otherwise be invisible to the naked eye. Binoculars are another popular astronomy tool, as they provide a wider field of view than telescopes and are easier to use. Planetariums are specialized theaters that create a realistic simulation of the night sky. They are often used to teach children about astronomy, as they can provide a much more immersive experience than looking at the sky through a telescope. Globes are also a valuable tool for teaching astronomy, as they provide a three-dimensional representation of the Earth and the planets. Star charts are maps of the night sky that show the constellations and other celestial objects. They can be used to help students learn to identify the stars and planets. In addition to these common pieces of equipment, there are many other specialized tools and materials used in astronomy education. These include spectrometers, which are used to study the light from stars and other objects; filters, which are used to block out unwanted light and improve the visibility of certain objects; and software programs, which can be used to analyze astronomical data. Astronomy school science equipment is essential for providing students with a hands-on learning experience. By using these tools, students can gain a deeper understanding of the universe and develop an appreciation for the wonders of science. Below is a list of common astronomy school science equipment used in both school and college laboratories: 1.Telescopes: Refracting telescopes Reflecting telescopes Catadioptric telescopes (combination of lenses and mirrors) 2.Mounts and Tripods: Equatorial mounts Altazimuth mounts Dobsonian mounts 3.Eyepieces and Barlow lenses: Various focal lengths for different magnifications 4.Filters: Solar filters Moon filters Light pollution filters 5.Star Charts and Planispheres: Celestial maps R otating star finders 6.Astronomy Software: Planetarium software Sky mapping applications 7.Cameras and Imaging Equipment: Astrophotography cameras CCD cameras DSLR cameras with adapters 8.Spectroscopes: Used for analyzing the spectrum of celestial objects 9.Solar Observing Equipment: Solar telescopes Hydrogen-alpha filters for solar viewing 10.Meteorites and Impactites: Samples for hands-on study 11.Orreries and Models: Mechanical models of the solar system 12.Globes: Celestial globes Terrestrial globes 13.Grating Spectrometers: Used for detailed spectral analysis 14.Laser Pointers: for pointing out celestial objects during presentations 15.Microscopes: for studying meteorite samples or microscopic features of celestial objects 16.Light Meters: for measuring ambient light pollution 17.Data Loggers: for recording observations and experiments 18.Educational Kits: Solar system model kits Planet and moon models 19.Laser Diodes: for optical experiments and demonstrations 20.Teaching Charts and Posters: Illustrations of constellations, galaxies, and other astronomical phenomena.

Unique Venues at the Houston Museum of Natural Science

Established in 1909, the Houston Museum of Natural Science (HMNS) is one of the best attended museums in the United States and one of the most popular attractions in Houston. HMNS at Hermann Park consists of five stories of permanent exhibits and rotating special events. The museum also manages a number of additional venues on site, including the Burke Baker Planetarium, the Cockrell Butterfly Center, and the Wortham Giant Screen Theatre.

The museum’s Burke Baker Planetarium opened to the public in 1964, and has since provided millions of visitors and field trip participants with a variety of astronomical programming. The planetarium has been updated several times over the decades, and now operates off the premier Digistar 6 digital planetarium software and projection system. Digistar 6 allows museum patrons to explore a multitude of cosmic settings, from planetary surfaces to asteroid fields. The Burke Baker Planetarium also hosts special events, such as high definition screenings of Pink Floyd’s The Dark Side of the Moon, and joint projects with other museum departments, including the Death of the Dinosaurs show.

The Cockrell Butterfly Center and Brown Hall of Entomology, meanwhile, make up one of the most interactive and visually stunning venues at HMNS. Children and families can walk through a living butterfly habitat, as well as an archive of preserved specimens, consisting of some of the largest and most interesting arthropods on the planet. As an educational resource for children, the center also features a number of puzzles and quizzes. From 2022 to 2023 the Cockrell Butterfly Center was temporarily closed to complete a number of renovations and improvements. New additions range from a three-story glass dome built over a 50-foot waterfall, designed to recreate a tropical rainforest environment, to the Cockrell Butterfly Center Flight School.

Finally, the Wortham Giant Screen Theatre became the first ever IMAX theater in the city of Houston when it opened it 1989. Over 16 million individuals have seen a movie or educational film at the 4K, high-dynamic-range screen. The screen measures 60 feet tall and 80 feet wide, and the stunning visual experience is supported by the latest in six-track sound system technology. Films screened at the Wortham Giant Screen Theatre address a myriad of historical and scientific subjects, including what the continent of Antarctica looked like during the time of the dinosaurs and the story of the Great Barrier Reef.

In addition to these venues at Hermann Park, HMNS operates the George Observatory and HMNS at Sugar Land. A collaboration between HMNS and Brazos Bend State Park, the George Observatory welcomes stargazers every Saturday night. Star-gazing options at the observatory include a range of deck and dome telescopes, live camera feeds, constellation laser tours, and a staff of amateur astronomers happy to guide newcomers through their first observatory visit. Individuals interested in a trip to the George Observatory should visit hmns.org for more information, as space and telescope access is limited.

HMNS at Sugar Land hosts a series of educational, interactive classes and exhibits for children and families, as well as special events and permanent exhibits. The venue has extensive experience running student labs and field trips with local schools. HMNS at Sugar Land is open all day from Thursday through Saturday.

Update on the saga of Preflight and Renderbox:

Both boxes have Internet. Our cable management is less likely to kill us now; we ran the Ethernet cables behind the piano.

Don’t ask about the piano.

We found a spare desk and gave it and the best behaved monitor we could find to Preflight, who is updating to Windows 10 as we speak.

Renderbox can now run modern planetarium software again, and quite well!! Go Renderbox!

We almost have that office in a usable state.

Thank god.

Astronomical photographer chasing China's space station

BEIJING, -- Stargazer, doctor of astrophysics, promoter of astronomy and vlogger -- Liu Boyang has many facets, but the most high-profile is his role as a documenter of China's space station.

In March, Liu began making preparations for his plan -- documenting and sharing the development of the space station so that he can "help more people learn about the development of China's aerospace sector."

"If you haven't captured and witnessed the changes of China's space station, it's hard to imagine that the space station flying above our heads can 'transform' like a robot," he said.

Since April 19, he has captured every configuration of China's space station on film.

In April 2021, the country officially kicked off the in-orbit construction of its space station by launching the core module Tianhe.

The space station features a basic three-module configuration consisting of the core module, Tianhe, and two lab modules, Wentian and Mengtian. It is designed to be a versatile space lab, capable of accommodating 25 experiment cabinets for scientific exploration.

As a full-time wemedia worker, the 32-year-old has spent months this year taking photos of the space station. However, his passion for astronomy goes back much further.

In 1990, Liu was born into an ordinary family in Erdos, north China's Inner Mongolia Autonomous Region. Before entering primary school, his parents took him to many museums and found that he took a special liking to planetariums.

In 1996, Liu received a significant gift -- an entry-level foldable telescope that cost his parents two months' salary.

When he was in senior high school, Liu joined the astronomy club and became one of its leaders, a role that required him to give lectures to other members. To present intriguing lectures, he read many astronomy books and surfed the internet to accumulate knowledge.

During the same period, he observed stars outside for the first time when he went on a stargazing trip with the other club members, using the school's only large aperture reflecting telescope.

"Astronomy does not live in history books, but in real life. Every moment, astronomical teams from across the globe make new discoveries, which help us feel the progress made by humans," he said.

In 2007, Liu's growing curiosity prompted him to major in astronomy at Peking University, and he later pursued his doctoral studies at the University of Western Australia.

During his doctorate years, he began to promote astronomical knowledge on his social media platforms. "We live in an era of the rapid development of science and technology, and it is very interesting to share what we have experienced."

In addition to popularizing astronomy, his idea to photograph artificial celestial bodies gradually came into being.

In 2020, he was surprised that foreign photographers could take close-up images of the International Space Station from the ground. He decided to try his hand at taking similar pictures.

However, photographing moving objects in space from the ground is not as simple as pressing the shutter button. Optical tracking software is needed to control telescope tracking. But the software he was able to find was either outdated or insufficiently designed to function properly.

On March 18 this year, Liu swung into action as he didn't want to miss the best stage to record the growth of China's space station. He decided to develop an optical tracking program himself.

On April 19, with his self-developed optical tracking program, Liu captured clear, close-up images of China's space station for the first time on the outskirts of Hengshui City, north China's Hebei Province, despite failures in the process.

Running after the space station was no easy task for Liu and his team, technically or financially.

The configuration of the space station is constantly changing with the completion of each launch mission. And the ideal conditions for observing and photographing the transit of the space station from the ground are very limited.

To look for better shooting conditions, he has made over 50 trips to carefully selected locations in more than 10 cities across the country, largely at his own expense. He waits patiently for the few minutes when the space station zips across the night sky.

This year, he traveled into the desert and onto plateaus, and almost got lost in the wild without a phone signal. But he says that the challenging experiences were "no big deal."

Thereafter, Liu's stories and the videos he shares garnered media attention, and subscribers flocked to his accounts on platforms including the Chinese online video-sharing platform Bilibili.

His Bilibili subscriber base grew from 2,000 in April to 100,000 in the end of September this year.

So far, he has captured 26 clear, close-up images of China's space station.

The space station will become busier exploring space science and technology in the coming years, as the recently launched Shenzhou-15 mission wraps up the last stage of the station's construction and kicks off the first stage of its application and development.

In addition to promoting astronomy, Liu is participating in the 6-8m Expanding Aperture Segmented Telescope project at Peking University, and he hopes his work will have scientific research and engineering value.

Best Telescopes for Viewing the Planets and Galaxies in High Resolution

The first step is to decide on the type of telescope you want to buy. There are two types of telescope: refractive and reflector. Refractors use lenses that focus light from the Sun and stars onto a lens, and reflector telescopes use mirrors to focus light onto a lens. Refractors are better for viewing the stars because they can see more detail in the stars than reflector telescopes. Reflector telescopes are excellent for viewing planets because they can see details in their atmospheres that other telescopes cannot see.

There are also different focal lengths that refractors have, ranging from 6 inches (15 cm) to 100 feet (30m). These focal lengths range from f/5 to f/8, with f/8 being the most common for most people. The focal length is measured in millimeters, so a telescope with a focal length of 50mm will have 50mm of glass at its focal point.

What's the Best Telescope for Astronomers?

A telescope is a device that allows you to see objects in the sky. It is used to observe stars and planets. There are different types of telescope. The most common ones are called refractors, reflectors, and telescopes with lenses.

The main purpose of a telescope is to enable us to see distant objects in the sky. In order to do that, we need a large aperture (the distance between the lens and the focal plane). The larger the aperture, the more distant objects can be seen. Aperture refers to how big or small an opening is on a telescope; it's measured in "dots" or "millimeters".

There are several types of telescope: refractors, reflectors and telescopes with lenses (telescopes with mirrors). Each type has its own advantages and disadvantages – it depends on what you want to do with your telescope.

The Top 5 Best Telescopes Guide for Astronomers

The world of astronomy is full of amazing things. Different telescopes are used by different people for different reasons. Some people want to observe stars and planets, others want to study the moon or galaxies closer to Earth. All these things require a lot of money and time, which is why we need telescopes that can be used for all these purposes.

The most reliable telescope reviews are available on various websites like Amazon, SkyWatcher etc. These reviews help us determine whether a particular telescope is good enough for our needs or not. Here we will focus on the most popular ones:

 How to Choose the Best Telescope for Your Needs

Choosing the right telescope for your needs is a very significant decision. This article will help you choose the right one.

We will start with basic information about telescopes and then we will go through all the possible options available to us.

There are two types of telescope. Refractors are suitable for astrophotography, but reflectors are better for viewing the night sky. Many people who want to see the stars and planets have both types of telescope, but they can't use them at the same time because they need different focal lengths (f/10 vs f/8). The number of lenses in each type of telescope is also different: 15 lenses in a refractor, 6 lenses in an 80mm reflector, 8 lenses in a 200mm reflector...and so on... So it's very critical that you choose your telescope carefully according to what you want to see! And don't forget that there is no pperfection

Telescopes are used for many things, including astronomical observations, observation of the night sky, and so on.

With the help of telescopes, we can observe planets and stars from a different perspective than what we see with our own eyes. We can also use them as a tool to study some things in more detail than is possible with our eyes.

The Planetarium Software Guide - How to Choose the Right Software

Being a planetarium software user, I have to say that the software is not as good as it could be. It has been so for several years now, and I have used it for more than 10 years.

I think that the main reason why the planetarium software is not as good as it could be is because of some of its problems. One of them is that when we are looking at star charts or at the sky, we can't see all the stars clearly. This can be fixed by adding an additional layer on top of this software which will show us all the stars clearly in their true colors.

Another problem with this type of software is that it doesn't provide any way to create your own star charts or sky charts on a computer screen (like you can do in Google Earth). This means that if you want to create your own star charts, you need to use planetarium software and then copy them onto your computer's clipboard (which would take time).
