Supernova Remnant Close to the Galactic Center Is 1,700 Years Old and Expanding at 2 Million MPH
There are things in this Universe the human mind simply has a very hard time understanding. Like, say, a supernova explosion caused by a star reaching the end of its life, an event so massive that, even 1,700 years after it happened, it can still shoot things into the surrounding Universe at two million miles per hour (3.22 million kph). We've known of supernovas for a long time now, so there are few things that keep us surprised ab... (continu…
