Deep space, Dark matter & Energy, The Suns incredible power, Diamond planets & Black holes are just a tiny fraction of the incredible things space has to offer, I hope you've enjoyed the video and if your interested in the possibility of life in space, then you may enjoy these two videos. Space is amazing. The sheer vastness of it, along with the trillions upon trillions of objects in the many billion galaxies of the universe is almost incomprehensible to the human brain. There is no atmosphere in space, which means that sound has no medium or way to travel to be heard. Astronauts use radios to stay in communication while in space, since radio waves can still be sent and received. The sheer size of space makes it impossible to accurately predict just how many stars we have. Right now, scientists and astronomers use the number of stars only within our galaxy, The Milky Way, to estimate. That number is between 200-400 billion stars and there are estimated to be billions of galaxies so the stars in space really are completely uncountable. As space facts go, this is pretty impressive. Research by Yale University scientists suggests that a rocky planet called 55 Cancri e — which has a radius twice Earth’s, and a mass eight times greater – may have a surface made up of graphite and diamond. It’s 40 light years away but visible to the naked eye in the constellation of Cancer.
