(PhysOrg.com) -- Studies of two supernova remnants using the Japan-U.S. Suzaku observatory have revealed never-before-seen embers of the high-temperature fireballs that immediately followed the...
View ArticleMassive white dwarf in our galaxy may go supernova
(PhysOrg.com) -- A massive white dwarf star in our galaxy may become a supernova several million years from now, and could damage the Earth and possibly destroy life on Earth.
View ArticleAstronomers simulate how white dwarf stars merge and become a supernova
(PhysOrg.com) -- Supernovae are spectacular events: Suddenly somewhere in the heavens a "new star" lights up and shines as bright as a whole galaxy consisting of billions of stars. The mechanisms...
View ArticleWhy Won't the Supernova Explode?
A massive old star is about to die a spectacular death. As its nuclear fuel runs out, it begins to collapse under its own tremendous weight. The crushing pressure inside the star skyrockets, triggering...
View ArticleFermi telescope closes in on mystery of cosmic ray acceleration
In all directions of the sky, cosmic rays rocket through space with incredible speed. These “rays”—which mostly consist of protons—are some of the most energetic particles in the universe. For nearly...
