Putting a damper on the feeling of immediacy the writer seems to have built into the piece, that star flamed out some 80 million years ago during our Cretaceous Period when T Rex, Triceratops et al roamed the earth!
- netcraft 9y agoWhile thats true, if the photographer had been a few days earlier or later their timing wouldnt have been right - so it is very much an immediate thing.
- mikekchar 9y agoYes, but T Rex, et al never made a note about it. Bloody typical! That's why it was such a last minute fiasco to take the picture. It's a miracle it got done, to be honest. Quite a bit like my job in some respects...
- quickthrower2 9y agoDoes 80 million light years mean 80 million years ago? If the star is moving away from us fast...
- Cthulhu_ 9y agoI think so; while it is moving away from us, 80 million years ago it exploded and sent its light our way. Because it's moving away from us, the light is stretched out a bit, causing red shift, allowing us to have a good idea of distance / time. I don't know how far the remains have traveled from us since then though.
