Found yourself ~spacing out~ recently? Or just generally a fan of astronomy and fun facts? We've rounded up a bunch of interesting facts about space that are truly out of this world. We might all just be tiny specks in a vast universe, but what a fascinating universe it is! Check out our out-of-this-world space facts below.
But wait, there’s more! Yes, space is cool, but there’s also a lot to learn about our very own planet and the beings that inhabit it — like these truly *fascinating* facts about the animal kingdom. (If you want to get more specific, we've also got dog facts, cat facts, and even shark facts!) Plus, we rounded up the most interesting facts we could find for anyone who wants to know a little more about, well, everything. Take your pick!
1. Undisturbed, footprints would last forever on the Moon.
2. If you fell into a black hole, you'd get stretched out like spaghetti.
3. It would take Usain Bolt — running at his highest recorded speed — a little over 262 days to trek the distance of Saturn's rings.
4. There are over 500,000 pieces of "space junk" floating above the Earth, and they're moving at speeds up to 17,500 mph.
6. The biggest star known to man is UY Scuti, which has a radius about 1,700 times larger than the Sun.
7. While Pluto isn't considered a planet anymore, there may be another planet in our solar system: "Planet Nine."
8. Anytime you look up at the sky, you are seeing the universe as it was in the past.
17. Do you still think you're all that? Jupiter's Great Red Spot in the center left of the photo above is roughly the size of Earth.
18. To match the energy the Sun produces, you would need to light 100 billion tons of dynamite every second.
19. If you weigh 100 pounds on Earth, you would weigh 1/100 of one pound on a comet, meaning you could just jump and you'd start floating off into space.
23. Scientists predict our Sun has 5 billion years left to live. However, humans most likely only have 1 billion years.
26. And in around 4.5 billion years, the Milky Way is expected to collide with the Andromeda galaxy, our closest galactic neighbor, to form a giant elliptical galaxy.
27. Did you know that all of the planets in our solar system can fit in between the Earth and the Moon, with about 2,729 miles to spare?
28. There is a planet in our galaxy where the temperature during the day can reach over 1,000 degrees Celsius, and it possibly rains molten glass horizontally at around 4,500 mph!
29. So we know that light takes a long time to travel through space, right? Well, there are actually some parts of the universe we can't see because the light from there hasn't reached us yet.
30. Although, soon the James Webb Space Telescope will allow us to explore galaxies that were formed at the very beginning of the universe, and observe stars forming planetary systems.
31. But here's the thing: There is such a phenomenon as the Kessler Effect, in which a single destructive event in Earth's low orbit could cause all satellites to break up into smaller and smaller fragments until the planet is surrounded by a massive cloud of shrapnel.
32. There's a rogue supermassive black hole speeding through space at around 5 million miles per hour.
35. It's possible for two pieces of the same metal to actually fuse together if they touch in outer space.
36. There are rogue planets that have been knocked out of orbit just chilling out in the universe, and they could do the same to another planet.
37. Dark matter is believed to be responsible for 85% of gravity in the universe, and no one knows what it is or how it works.
38. According to quantum mechanics, there's a small chance the entire universe could spontaneously disappear and never come back.
39. This isn't a fact per se, but have you considered the possibility that we've already sent a message to an alien race in the distant past and it's still making its way to them?
41. There’s a gas cloud in the constellation of Aquila that holds enough alcohol to make 400 trillion trillion pints of beer.
48. More solar energy reaches Earth's surface in an hour and a half than we used in the whole of 2001.
