The biggest star known to man is 1,700 times larger than the sun!
4. And in around 4.5 billion years, the Milky Way is expected to collide with the Andromeda galaxy, our closest galactic neighbour, to form a giant elliptical galaxy.
6. And our big ol’ red neighbour, Jupiter, is twice as big as all of the other planets in our solar system combined!
7. 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!
8. Scientists think they have found a parallel universe in a void measuring one billion light years across.
9. 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.
10. 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.
12. Did you know that there are an estimated 500,000 pieces of space debris floating above the Earth and moving around at speeds of up to 17,500 mph?
14. 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.
15. There’s a rogue supermassive black hole speeding through space at around five million miles per hour.
22. And lastly, 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?
