In space, explosions of actual stars are a focus for scientists who hope to better understand the lifecycle of their births, lives, and deaths. (2015-03-20)


NGC 6240 in 60 Seconds

View/Listen
Narrator (Megan Watzke, CXC): NGC 6240 is a system in which two supermassive black holes are a mere 3,000 light years apart, virtually nothing in astronomical terms. These black holes -- the two bright point-like sources in the middle -- are in such close proximity, scientists think they are in the act of spiraling toward each other. This is a process that began about 30 million years ago. It's estimated that the two black holes will eventually drift together and merge into a larger black hole some tens to hundreds of millions of years from now.
