Ok can someone explain this.... I can't wrap my tiny brain around it...
We are seeing this, but not really? It's 600 million light years from Earth so are we are seeing this from 600 million years ago?
So they are saying its about to go Supernova and be as bright as the moon... within the the next 10,000 years.
But we can only see it as looked 600 million years ago? So it's long, long dead. It actually would have exploded when the Dinosaurs were around?
