Jet From Supermassive Black Hole Seen Blasting Neighboring Galaxy is an interesting article from the Washington Post. Apparently, astronomers have found a black hole that is sending a gigantic stream of deadly radiation into a neighboring galaxy -- good for birthing stars, but quite bad for any life that might have been in the path of that radiation.
Yet another thing for people to fear: intergalactic radiation that suddenly wipes out Earth's atmosphere and magnetic field. Apparently the researchers that saw this think that the same thing could actually happen to the Milky Way in about a billion years, when it starts merging with the Andromeda galaxy. Well, look on the bright side: maybe our sun will have imploded by then, anyway.
I have to say, this sort of thing really strikes me as interesting partial-premises for sci-fi novels. I know that a lot of the far-future dying-sun stories have already been done, but I still hunger to someday do something of the sort. There are just too many interesting ideas to write them all!
