The Universe is full of stars and planets and asteroids and satellites and MYSTERIES! It is a huge structure full of complex things which no one can fully understand. The vastness of the universe has astonished mankind from the start. Here are some astonishing facts about the universe that will amaze you.
#1 You can look back in time
Okay, so we all know that light travels (obviously) and that the stars are many light years away from us. So for example, if a star is 20 light years away from us, it means that the bright version of the star that you are seeing is 20 years old. It is from the past!! Ain’t that crazy?
#2 Journey of the Sun
One more fact about our universe is that it revolves, and every single celestial body of the universe also revolves around something. The sun does too. It takes around 225 million years for the sun to complete its revolution around the galaxy. 225 million years! Just take it in.
