Black (Hole) Friday!

It’s Black Friday, but for us, it’s the annual Black Hole Friday! Today, we’ll post awesome images and information about black holes.

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space…sort of like all of those shoppers trying to fit into the department stores today.

Because no light can get out, you can’t see black holes with the naked eye. Space telescopes with special tools  help find black holes (sort of how those websites help you find shopping deals).

How big are black holes? Black holes can be large or small…just like the lines in all of the stores today. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain! 

So how do black holes form? Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star collapses. When this happens, it causes a supernova. 

A supernova is an exploding star that blasts part of its mass into space. 

Supermassive black holes are an altogether different story. Scientists think they were made at the same time as the galaxy they in they reside. Supermassive black holes, with their immense gravitational pull, are notoriously good at clearing out their immediate surroundings by eating nearby objects. When a star passes within a certain distance of a black hole, the stellar material gets stretched and compressed – or “spaghettified” – as the black hole swallows it. A black hole destroying a star, an event astronomers call “stellar tidal disruption,” releases an enormous amount of energy, brightening the surroundings in an event called a flare. In recent years, a few dozen such flares have been discovered.

Then there are ultramassive black holes, which are found in galaxies at the centers of massive galaxy clusters containing huge amounts of hot gas.

gosh but like we spent hundreds of years looking up at the stars and wondering “is there anybody out there” and hoping and guessing and imagining

because we as a species were so lonely and we wanted friends so bad, we wanted to meet other species and we wanted to talk to them and we wanted to learn from them and to stop being the only people in the universe

and we started realizing that things were maybe not going so good for us— we got scared that we were going to blow each other up, we got scared that we were going to break our planet permanently, we got scared that in a hundred years we were all going to be dead and gone and even if there were other people out there, we’d never get to meet them

and then

we built robots?

and we gave them names and we gave them brains made out of silicon and we pretended they were people and we told them hey you wanna go exploring, and of course they did, because we had made them in our own image

and maybe in a hundred years we won’t be around any more, maybe yeah the planet will be a mess and we’ll all be dead, and if other people come from the stars we won’t be around to meet them and say hi! how are you! we’re people, too! you’re not alone any more!, maybe we’ll be gone

but we built robots, who have beat-up hulls and metal brains, and who have names; and if the other people come and say, who were these people? what were they like?

the robots can say, when they made us, they called us discovery; they called us curiosity; they called us explorer; they called us spirit. they must have thought that was important.

and they told us to tell you hello.
