Washington, February 15 (ANI): Analysis of data from NASA's Fermi Gamma-ray Space Telescope has provided the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe.
Rare explosion may have created our galaxy's youngest black hole Feb 14, 10:06 am
Washington, February 14 (ANI): A highly distorted supernova remnant may contain the most recent black hole formed in the Milky Way galaxy, new data from NASA's Chandra X-ray Observatory have suggested.
Massive star explodes few days before supernova explosion Feb 8, 3:38 pm
London, February 8 (ANI): Scientists have observed an outburst taking place a short time - just one month - before a massive star underwent a supernova explosion.
Washington, February 6(ANI): Scientists have made a major step forward in understanding the structure and behavior of some of the most elusive atomic nuclei in existence, some of which occur only briefly on the surface of exploding stars, thanks to the first set of experiments from the new Advanced Gamma Tracking Array (AGATA).
Secret life of binary stars revealed Jan 25, 11:59 am
Washington, January 25 (ANI): In a new study, researchers have revealed the workings of a celestial event involving binary stars that results in an explosion so powerful it ranks close to supernovae in luminosity.
Washington, January 23(ANI): New image from ESA's Herschel space observatory has revealed multiple arcs around Betelgeuse, the nearest red supergiant star to Earth, and scientists analysing the image have suggested that the star and its arc-shaped shields could collide with an intriguing dusty 'wall' in 5000 years.
Washington, January 21 (ANI): A new view of a 20,000-year old supernova remnant using the National Science Foundation's (NSF) Karl G. Jansky Very Large Array (VLA) has provided more clues to the history of this giant cloud that resembles a beloved endangered species, the Florida Manatee.
