The BBC reports: "Star dies in monstrous explosion". The Headline and everything else in the story is using the wrong tense.
The star in question is some 240 light years from earth. That means that the star exploded 240 years ago and the light is
just reaching us now. Scientists are watching another star, expecting it to explode... guess what? It's already gone. When
you look into space, you are looking into the past. I sometimes wonder if the star I'm seeing is still there. Well, one of
them isn't and it's been gone for sometime.
