What is the nearest supernova candidate (maybe Betelguese?) to the Earth?
Where is HR8210 located in the sky? It's amazing that a simple search under HR8210 doesn't bring up anything with a location. Thanks.LURCH said:That would be HR8210, discovered sometime in the 90's, but only recently recognised as a type-1 supernova candidate. It's only about 150 ly away, and be the end of us if it went off now.
