I found out about this from here.

11.4 million years ago, a star went supernova.  And we (the human race) just noticed it.  Within the past month.  Think about that.  The article has pictures from an observatory in London — one taken in mid-December and one taken in mid-to-late January — showing the explosion of a star.    The earth is going to be witness to something that happened 11.4 million years ago.  Possibly with binoculars.

I would love to know which way to point a 300mm telephoto camera lens to try to pick up on this, but I doubt with all the interfering lights from suburbia I will be able to see anything.
