I have a friend who is writing a supernatural fantasy. I've been reading his chapters and it's really good, the kind of story that makes the little hairs on your neck stand up. But here's the weird part. The opening chapter is called "Birth of the Bear Star" and it features two characters witnessing a supernova...in Ursa Major. In case you're not up on your astronomical events, a star in the Ursa Major constellation went supernova this week. I've told him he'd better be VERY careful about the other events he writes into his tale. Here's an article about the event.
