This is one of the strongest solar storms in ages. View from ISS is incredible.

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

Happy (extremely belated) moon day!

To celebrate here's a fun fact: the south pole-aitken basin feature is the largest impact feature on the moon, spanning 2500 km of diameter and 13 km of depth. The SPA is one of the primary objects of interest for future Artemis missions and research due to what it can tell us about the history of the solar system and the formation of the moon!

Orion’s Belt is always pointed to Sirius.

let me take a moment to share my all-time favorite astrophysics quote of all time:

“the center of the sun is more like a collection of 70,000 toasters than a nuclear war”

said by my favorite guy Joshua Winn, professor of astrophysics at Princeton

the explanation? the sun is very WSHOOO, BOOOM, explode-y on the outside, everyone knows that, but the core is just very, hmmm :) very calm. very warm. and the energy output, per cubic meter, at the center of the sun? about as much as one regular sized toaster. and the core of the sun is roughly 70,000 m^3, so, if you were to suspend 70k toasters in air, about a meter apart from each other in all directions, you would have a rough adaptation of the center of the sun :D hence, “the center of the sun is more like collection of 70,000 toasters than a nuclear war” :DDD

Ya know what’s sad?

The last words from anyone in the Challenger crew were the pilot, Mike Smith, saying, “Uh oh,” as the pressure in one of the tanks dropped :(( 💔

Space Just Dropped a Lemon... Literally. Forget what you learned in science class—not every planet is a perfect sphere.

Astronomers have confirmed the existence of PSR J2322-2650b, a gas giant that looks less like a marble and more like a giant cosmic lemon.

It orbits a pulsar so closely that the star’s gravity is stretching the planet’s entire mass into an oval shape.

Because of the intense pressure and carbon-rich atmosphere, it likely rains diamonds at the "tips" of the lemon. The atmosphere is essentially made of molecular soot.

It’s a reminder that the universe is way weirder than we can imagine.

My name is Nebulanarrator. I love space. Idk what took so long to draw it.

Fun fact: Did you know that the death of a star is so rare, like, only one star explodes in the Milky Way every couple of years. But like, stars go supernova constantly all the time since our universe is so big.

To put you into perspective, we are smaller than grains of sand compared to the Milky Way. Our universe is a bunch of those galaxy clusters (groups of galaxies) and empty space. one light-year is roughly 150 million Earths lined up, or about 236 million times the Earth's circumference. It takes 55 of that to get to the closest black hole in the Milky Way. The biggest black hole discovered has a diameter of two Milky Ways.

Humans are tiny. And that's way less than an exaggeration. They're probably smaller than tiny, even atoms, compared to the sun alone. Even our sun isn't that big. It's medium-sized for a star.

So yeah, Humans are tiny
