DC X DP PROMPT #4
Danny was one of the people hired to design/build the Watchtower. He got attached to it during this time and the space station is now considered as a part of his haunt.
This is the JLD's first time on the Watchtower, they IMMEDIATLY know what's up.
LJD: did you take a supernatural entities property or something?
LD: what? No! The lights are just like that :)
Danny, still employed on the Watchtower: Space go brrr
#dc x dp#dpxdc#im goiny crazy#im actually cooking#danny MADE the watchtower#thats HIS place now#JLD rockin up being like: whos crib is it really?#poor JL being liek: wdym :( we got this for us :(((#JL: i mean the light flicker and it get weird cold soemtimes but its space man :(#dannt lives on the Watchtower via employment

A Tour of Cosmic Temperatures
We often think of space as “cold,” but its temperature can vary enormously depending on where you visit. If the difference between summer and winter on Earth feels extreme, imagine the range of temperatures between the coldest and hottest places in the universe — it’s trillions of degrees! So let’s take a tour of cosmic temperatures … from the coldest spots to the hottest temperatures yet achieved.
First, a little vocabulary: Astronomers use the Kelvin temperature scale, which is represented by the symbol K. Going up by 1 K is the same as going up 1°C, but the scale begins at 0 K, or -273°C, which is also called absolute zero. This is the temperature where the atoms in stuff stop moving. We’ll measure our temperatures in this tour in kelvins, but also convert them to make them more familiar!
We’ll start on the chilly end of the scale with our CAL (Cold Atom Lab) on the International Space Station, which can chill atoms to within one ten billionth of a degree above 0 K, just a fraction above absolute zero.

Just slightly warmer is the Resolve sensor inside XRISM, pronounced “crism,” short for the X-ray Imaging and Spectroscopy Mission. This is an international collaboration led by JAXA (Japan Aerospace Exploration Agency) with NASA and ESA (European Space Agency). Resolve operates at one twentieth of a degree above 0 K. Why? To measure the heat from individual X-rays striking its 36 pixels!

Resolve and CAL are both colder than the Boomerang Nebula, the coldest known region in the cosmos at just 1 K! This cloud of dust and gas left over from a Sun-like star is about 5,000 light-years from Earth. Scientists are studying why it’s colder than the natural background temperature of deep space.

Let’s talk about some temperatures closer to home. Icy gas giant Neptune is the coldest major planet. It has an average temperature of 72 K at the height in its atmosphere where the pressure is equivalent to sea level on Earth. Explore how that compares to other objects in our solar system!

How about Earth? According to NOAA, Death Valley set the world’s surface air temperature record on July 10, 1913. This record of 330 K has yet to be broken — but recent heat waves have come close. (If you’re curious about the coldest temperature measured on Earth, that’d be 183.95 K (-128.6°F or -89.2°C) at Vostok Station, Antarctica, on July 21, 1983.)
We monitor Earth's global average temperature to understand how our planet is changing due to human activities. Last year, 2023, was the warmest year on our record, which stretches back to 1880.

The inside of our planet is even hotter. Earth’s inner core is a solid sphere made of iron and nickel that’s about 759 miles (1,221 kilometers) in radius. It reaches temperatures up to 5,600 K.

We might assume stars would be much hotter than our planet, but the surface of Rigel is only about twice the temperature of Earth’s core at 11,000 K. Rigel is a young, blue star in the constellation Orion, and one of the brightest stars in our night sky.

We study temperatures on large and small scales. The electrons in hydrogen, the most abundant element in the universe, can be stripped away from their atoms in a process called ionization at a temperature around 158,000 K. When these electrons join back up with ionized atoms, light is produced. Ionization is what makes some clouds of gas and dust, like the Orion Nebula, glow.

We already talked about the temperature on a star’s surface, but the material surrounding a star gets much, much hotter! Our Sun’s surface is about 5,800 K (10,000°F or 5,500°C), but the outermost layer of the solar atmosphere, called the corona, can reach millions of kelvins.
Our Parker Solar Probe became the first spacecraft to fly through the corona in 2021, helping us answer questions like why it is so much hotter than the Sun's surface. This is one of the mysteries of the Sun that solar scientists have been trying to figure out for years.

Looking for a hotter spot? Located about 240 million light-years away, the Perseus galaxy cluster contains thousands of galaxies. It’s surrounded by a vast cloud of gas heated up to tens of millions of kelvins that glows in X-ray light. Our telescopes found a giant wave rolling through this cluster’s hot gas, likely due to a smaller cluster grazing it billions of years ago.

Now things are really starting to heat up! When massive stars — ones with eight times the mass of our Sun or more — run out of fuel, they put on a show. On their way to becoming black holes or neutron stars, these stars will shed their outer layers in a supernova explosion. These layers can reach temperatures of 300 million K!

We couldn’t explore cosmic temperatures without talking about black holes. When stuff gets too close to a black hole, it can become part of a hot, orbiting debris disk with a conical corona swirling above it. As the material churns, it heats up and emits light, making it glow. This hot environment, which can reach temperatures of a billion kelvins, helps us find and study black holes even though they don’t emit light themselves.
JAXA’s XRISM telescope, which we mentioned at the start of our tour, uses its supercool Resolve detector to explore the scorching conditions around these intriguing, extreme objects.

Our universe’s origins are even hotter. Just one second after the big bang, our tiny, baby universe consisted of an extremely hot — around 10 billion K — “soup” of light and particles. It had to cool for a few minutes before the first elements could form. The oldest light we can see, the cosmic microwave background, is from about 380,000 years after the big bang, and shows us the heat left over from these earlier moments.

We’ve ventured far in distance and time … but the final spot on our temperature adventure is back on Earth! Scientists use the Large Hadron Collider at CERN to smash teensy particles together at superspeeds to simulate the conditions of the early universe. In 2012, they generated a plasma that was over 5 trillion K, setting a world record for the highest human-made temperature.

Book 2 au: and there was only one bed!! :00
Because of course I just had to do this trope
This is the first and last time they decide to sleep in an inn and they have an unspoken agreement to pretend this never happened
#zutara#zuko#katara#atla#book 2 au#my art#i like to think katara is pretty clingy when sleeping cause she's from the south pole#and she's probably really used to cuddling in order to share body heat to get through the really cold nights#ofc she'd usually be cuddling up with her family and not the banished prince of the fire nation who's also pretending to be her husband#zuko on the other hand is not used to sharing a bed with anyone much less sharing his personal space and cuddling with anyone#but anyways zuko would rather die than admit he didn't mind it as much as he thought he would and that he slept comfortably well that night#to the anon that was just asking about this au this one's for you lolol#i told you i was just about to post something and here it is

Dragging you outside to go stare at the moon and stars before kissing you
#wlw#wlw mood#sapphic#sapphism#lesbian#jk if we’re kissing how will i look at SPACE#i am NOT immune to the inherent beauty and romance of the universe#my toxic trait is how often i go to look at stars in the middle of winter#come be cold with me <33333#we get to see the night sky AND go in and cuddle under blankets#literally no downside😤#im gay and i like sleeping

"we need more complex female characters" you couldn't even handle her
#ash: hey idk if it’s a good idea to give full access of the most advanced warship we have to a mercenary who shot a suspect in cold blood#and a cop who quit his job because there were too many rules (and also happens to be a member of the military we were recently at war with)#also i think the council will throw us to the wolves to save themselves#like half the fandom: omg space racist???#sorry for discourse posting™ but i saw a terrible post that rocketed me back into 2013#anyway we may have preferences but we love and appreciate both virmire survivors in this house#mass effect#ashley williams

Some Symptoms of ADHD from Someone who is diagnosed:
Forgetfulness that impacts daily life
Difficulty remembering others names and even faces
Hard to stop fidgeting or moving when bored. Difficult to stop even when aware
Hyperfocus
Lack of motivation in tasks, even more so when external motivations are not given
Difficulty in being organized for extended periods of time
[[Symptoms of Adult ADHD]]
#on a post from a week ago I saw so many people talk about their ADHD and the stigma around it#and i just had a really good conversation with one of my friends about ADHD and.... I just want to create a safe space here for it#ADHD is awful and not enough people talk about how truly detrimental it can be. You gaslight yourself. You mask. You feel shame.#it is so so important for me to create a safe space for people here about ADHD. And people NEED to understand our struggles.#i am literally making this post in a cold sweat because I had this thought in the car AND I HAD TO MAKE THIS POLL#ADHD#adhd problems#bread#my polls
