Using MAGIC telescopes and NASA's Fermi spacecraft, an international team of astronomers has discovered a new source of very high energy gamma-ray emission around the supernova remnant (SNR) G24.7+0.6. The detection of the ...
Because the debris fields of exploded stars, known as supernova remnants, are very hot, energetic, and glow brightly in X-ray light, NASA's Chandra X-ray Observatory has proven to be a valuable tool in studying them. The ...

(Phys.org)—An international team of astronomers has uncovered molecular and atomic gas clouds associated with the superbubble known as 30 Doradus C, which is located in the Large Magellanic Cloud (LMC). The findings were ...
(PhysOrg.com) -- Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory ...
