15 Impossible Things Astrophysics Says Are Actually True

The universe keeps doing things that sound flat-out impossible, and astrophysics keeps confirming them. A star that refused to stay dead, planets lighter than cotton candy, a black hole thinner than the air you breathe, and a supernova astronomers predicted before it showed up. Fifteen real discoveries, real names, real data, and the strange reasons each one turned out to be true.
