Description

There’s a bright supernova in a nearby galaxy, and a very distant supernova made brighter by the beauty of gravitational lensing. In another galaxy, a gargantuan black hole is revealed to be orbited by another supermassive black hole, resulting in a gamma ray flares as it rips through the main black hole’s accretion disk. Closer to home, we learn about new asteroid missions and a rapidly warming planet (hint: it’s ours). Plus: Harrison Ford and Leonard Nimoy trivia!
