(PhysOrg.com) -- An amateur astronomer working from his backyard shed in Ireland was the first in the world to spot a supernova explosion last month. The discovery is the biggest ever in amateur astronomy in Ireland.
(PhysOrg.com) -- In the past decade, robotic telescopes have turned astronomers' attention to scads of strange exploding stars, one-offs that may or may not point to new and unusual physics.
