|MadSci Network: Astronomy|
I was reciently reading about the (galactically speaking) impending supanova which I read would be bright enough to make it seem like we had 2 suns in the sky. If this were the case.. would it be warm like the sun? And would it gradually get brighter when the light reached us or would it be instantly from night to day (assuming it reached us during our night)? And what colour light would it be?
Re: Will the light from betelgeuse be hot?
