everyone say thank you to the vacuum of space

[ocean-sunfish-apathy]

fact: one million earths could fit inside the sun. and at least that many sunfish could fit inside the earth. maybe more

[i-am-inside-your-bones]

Here’s a fact for you

You, yes you, are a rarer phenomenon then a black hole

You are rarer than any kind of star

You are rarer than a supernova

You are statistically the most rare, most special, and most interesting event in the universe

There is a confirmed 0% chance that something else can be you, as you are.

You even being born was a 1 in 400 trillion chance

You, just you, are amazing

Super Cosmic Space Fact of the Day!!

The Veil Nebula (specifically Caldwell 33) isn't a cloud. It's what happens when a star violently blows its guts all over space and leaves the cosmic splatter glowing for the next several thousand years

It sits at about 2,000 light-years away in the constellation Cygnus, it's a colossal shockwave still racing through space. The entire remnant spans roughly 110 light-years—so large that, from Earth, it covers an area of sky about six times wider than the full Moon.

Here's the part that matters to you. Stars like this don't just explode, they're the universe's heavy-element factories; The supernova forged elements heavier than iron, including gold, copper, lead, mercury, and iodine, before blasting them into space. Those atoms eventually mixed into giant clouds of gas and dust that formed new stars, new planets... and, billions of years later, you.

The Veil Nebula is also one of astronomy's favorite laboratories. Because it's relatively close and unobscured, telescopes like Hubble can watch its shockwaves slam into surrounding gas, stretching it into those impossibly thin, glowing filaments. Those aren't random wisps—they're the visible edge of an explosion that's still expanding after thousands of years. And the Veil is only one section of an even larger structure called the Cygnus Loop, one of the best-studied supernova remnants in the Milky Way. Every ripple, filament, and glowing arc is another piece of data explaining how dying stars recycle themselves into the next generation of worlds.

So the next time someone says we're made of stardust, don't roll your eyes. They're majorly underselling it—What you’re actually made from is the aftermath of stars that exploded with enough force to reshape an entire corner of the galaxy. And that’s ten billion percent cooler.

If we as humans can only see for approximately a mile due to the spherical nature of earth creating a horizon, how far can we see in space since it doesnt curve?

It's impossible to get a boner while in space so the ISS crew has to mostly do mouth and hand stuff.
