I guess that drives a final nail through the coffin of my hopes of seeing a supernova in my lifetime.
Yes because they always get it right......RIGHT?
It’s 2020, so don’t give up hope yet.
Some argue that as our Sun crosses the galactic current sheet it goes micronova, it's not a supernova, but it is a LOT closer!
It's periodic, with a periodicity of about 12,000 to 13,000 years...
They happen quite frequently actually. Now they may not be visual except with a telescope, but, they are visible. Then there was 1987a in the SMC. Don’t give up! Keep an eye out in www.skyandtelescope.com or spaceweather.com. They post when someone finds a supernova in a neighboring galaxy. Then use your scope, or, find someone with one, to look at it.
