Given that each light-year — defined as the distance light travels in one Earth year — is about 6 trillion miles (9 trillion km), a black hole that lies 1,000 light-years away may not seem very close. However, to astronomers who are accustomed to cosmic distance scales, the recently-discovered HR 6819's black hole, which lies in the constellation Telescopium, is an extremely close neighbor.

        That is so cool it is to bad that Stefan Hawking isn’t her to see it. Every time I hear that name I remember him. He proved so many things like no matter the obstacle you can always succeed all you have to do is try. “One, remember to look up at the stars and not down at your feet.” Stefan Hawking. Rest In Peace. 😥
