These

I did these as a contrast of this two like cold and hot lmao

(If you put one over the other Kori and Taiyo will be side to side)

Personally I think that Azula should have been redeemed simply so that she can become Zuko's horrible little advisor who whispers evil little plans to him so that he can do the exact opposite

I've heard my wildlife ecology professors describe moose as "exquisitely cold adapted" so many times that the word exquisite instantly makes me think of moose now.

getting older can be so amazing? you get more familiar with yourself. learn tips & tricks for troubleshooting your own brain. trial & error helps you build routines that minimize discomfort, maximize reward. your preferences/interests don't get set in stone, but you do find out which ones are going to stay with you in the long-term, and which ones are fun but transient joys to appreciate in the moment.

you learn that the world is so much more complex than you were taught, and that that's okay, and that there's an endless supply of things you can learn or watch or experience or think about if you want to. if you're lucky, you loosen up, stop putting so much pressure on yourself. if you're lucky, you learn to recognize that negative inner voice, and whack it with a baseball bat until it hushes up. if you're lucky, you learn to treat yourself gently, not because you are fragile but because you are worthy of gentleness. (i hope you are lucky.)

and some things will change. some things will get better. some things will get good. and maybe you start to recover from the dehumanizing stress of childhood/education. maybe you learn the power of your own autonomy. maybe you learn how to walk away from bad situations (which is a superpower even if you don't realize it yet). and you get to choose your own clothes. and your own food. and which relationships to pursue! and what you do with your free time. and with your life (but don't worry you get to choose that gradually). and that's crazy! and sometimes scary. and extraordinarily, indescribably precious.

IS IT A COINCIDENCE? I THINK NOT

[bigfatbreak]

Something I've always been curious about with your amazing Changeling AU, can everyone see the transformations the changeling kids go through in the comics? Or is it like something only those with special eyes/some level of awareness of what the fae and changelings are can pick up on?

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.

April 11

cold and hot

i felt a fullness in the cold today

my entire body responding to chill

that cold often described as empty

as a lack

and yes arguably

warmth has more presence

more weight and more texture

but such qualities set it up

to be so overbearing

i fail to remember a refreshed feeling

while under the heel of heat

cold is a snap

sharp and precise

reminder to synapses to keep on firing

a discomfort that finds itself necessary

yet that pinpoint precision

like the burden of heat

can become overwhelming

and leave you numb

a body overridden

subsumed by the temperature

you no longer feel cold

you are it

balance seems logical

that often found answer

musings relating to moderation and equilibrium

and while there’s enough satisfaction

to be found in the lukewarm

still there’s that bias

poking my soul

how a warm person shines

while a cold person skulks

we can find compromise

in the realm of the body

but who calls for fairness

in the realm of the mind

burn with a passion

freeze in reflection

it is not good and evil

but binary waiting to congeal
