501 Facts Factory: Amazing Things You Should Know about Space

Gayathri Ponvannan

Did you know * We're moving through space at a speed of 3,000 km in ONE second! * The sun once had a twin! * When some stars die, they turn into black holes. Humans have been peering at the skies for ages, trying to figure out just what lies beyond us. And over these years, we've managed to figure out a lot of stuff. For instance, we now know that the Earth goes around the sun; and that the sun goes around a supermassive black hole. We've calculated the speed of light, the brightness of stars and the temperature of the universe at the very first moment of its existence. And there's some stuff we're still figuring out - like the quantum foam in an atom; the power of dark energy that's fuelling the universe; the ingredients of the soup that once filled the universe. This book is filled with many such fascinating facts about our planet and our surroundings. You'll learn about what makes up everything in the universe, from stars to you (hint: it's the same stuff!). You'll learn about our universe's past and what might happen to it in the future. And you'll learn about the scientists, astronomers and physicists who made these amazing discoveries (and weird mistakes) that help us make sense of all the mysteries around us.
