Isn't the closest and biggest supernova candidate, Eta Carina??
It looks awesome in my scope, and whenever I look at it I hope it to go pop so I can phone up someone and claim the honour of being first
Then there is this concentrated beam of particles coming off a black hole that could fry us if it was pointed at us.
I think I'll take a chance and cook up the roo fillet on the barbie anyway
