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.
