"The speed at which this doomed stellar system is lurching wildly, likely due to the extreme brightness, is a frantic sign of ...

Most stars in the Milky Way move at steady speeds, orbiting the galactic center in regular paths. But astronomers have ...

Scientists have turned to artificial intelligence (AI) to better understand why some dead stellar remnants called white dwarf stars explode. These energetic explosions, called Type Ia supernovas, ...

Berkeley Lab astrophysicist Peter Nugent, working with Adam Riess of the Space Telescope Science Institute, used an IBM SP supercomputer at NERSC to analyze data from an exploding star that had been ...

When a dense stellar core called a white dwarf acquires enough material from a companion star orbiting nearby, it burns up in the nuclear fusion blast of a Type Ia supernova. This ejects freshly ...

May 8 (UPI) --The discovery of Type Ia supernovae with hydrogen, a rarity, could help astronomers trace the origins of the explosive cosmic phenomena. Type Ia supernovae occur when the white dwarf in ...

Astronomers have found solid evidence about what triggered a star to explode, which will contribute to a further understanding of supernova history and behavior. An international team of researchers ...

In 1996, an archaeologist named Aly A. Barakat was doing fieldwork in an Egyptian desert and stumbled across an unusual shiny black pebble now known as the Hypatia stone (after Hypatia of Alexandria).
