Total Annihilation of Supermassive Stars

A renegade star exploding in a distant galaxy has forced astronomers to set aside decades of research and focus on a new breed of supernovae that can utterly annihilate its parent star — leaving no remnant behind. The signature event, something astronomers had never witnessed before, may represent the way in which the most supermassive ...

Unusual Supernova Opens a Rare Window on the Collapse of a Star

An unusual supernova studied by multiple telescopes, including the SOAR telescope and other telescopes at the National Science Foundation’s (NSF) Cerro Tololo Inter-American Observatory (CTIO) and NSF’s Kitt Peak National Observatory (KPNO), is thought to herald the birth of a new black hole or neutron star, caught at the exact moment of its creation. Observations ...

Study Witnesses First Moments of a Star Dying in Finest Detail

An international research team, including The Australian National University (ANU), has used the Kepler space telescope in coordination with ground-based telescopes to witness the first moments of a star dying in unprecedented detail. The astronomers witnessed the star dying a long time ago in a galaxy far, far away, as part of a project that ...
