A new model for matter in neutron star collisions. After a massive star burns its fuel and explodes as a supernova, an exceedingly compact object…
Detailed telescope images help scientists learn more about the Universe two billion years after the Big Bang. An international research team has measured the size…
Modeling calls into question supernova origin, forcing a reconsideration of the prevailing view of gamma-ray-burst events. The standard view of gamma-ray bursts as a signature…
The study reveals cosmic rays are driving galaxies’ winds An important new hint regarding how galaxies halt intense episodes of star formation has been found…
What do you see in this intricate image of the Vela supernova remnant? A spooky spider web, magical dragons, or wispy trails of ghosts? This…
Evidence of a first-generation star that died in a “super-supernova” explosion is discovered by Gemini’s observation of a far-away quasar. The ancient chemical remains of…
NASA’s Swift and Fermi Missions Detect Exceptional Cosmic Blast An unusually bright and long-lasting pulse of high-energy radiation swept over Earth Sunday, October 9, captivating…
A new study creates the first map of our galaxy’s ancient dead stars. In the first map of the ‘galactic underworld’, a study from the…
Astronomers from Liverpool John Moores University and the University of Montpellier have devised an ‘early warning’ system to sound the alert when a massive star…
A Tenacious Star Validates a Revised Model of Supernovae A supernova is the cataclysmic explosion of a star. Thermonuclear supernovae, in particular, signal the complete…
Scientists from the RIKEN Cluster for Pioneering Research have used computer modeling to show how a hypothesized type of supernova would evolve on the scale…
New chemistry ‘forensics’ indicates that the stone named Hypatia from the Egyptian desert could be the first physical evidence found on Earth of a supernova…
Western Sydney University researchers, together with an international team of experts, have discovered a mysterious circular ring near our neighboring galaxy that could be the…
Study including University of Chicago researchers analyzes aftermath of 2014 supernova. An international group of astronomers has uncovered new clues about a mysterious stellar explosion…
The discovery helps explain the puzzle of hydrogen loss pre-supernova, and supports the theory that most massive stars are paired. It’s not unheard of to…
A multinational team of astronomers led by Benjamin Thomas of The University of Texas at Austin has used observations from the Hobby-Eberly Telescope (HET) at…
Gamma ray observatory H.E.S.S. reveals a cosmic particle acceleration process in unprecedented detail. With the help of special telescopes, researchers have observed a cosmic particle…
