V Sagittae’s violent mass transfer hints at an imminent nova—and a future supernova visible from Earth. Binary star systems are fairly common in the universe, as are pairs where one star is a compact ...

The first double-burst supernova ever observed, SNR 0509, is a historic discovery that reveals how white dwarfs explode in the cosmos.

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 ...

A study looking at ancient texts may have found evidence of a galactic supernova in a poem praising Saladin, the first sultan ...

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 ...

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).

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 ...
