The "Per-Tau shell," which extends for nearly 500 light years, solves a big mystery and has implications for astrophysics as a whole.
A rare natural fission reaction might detonate white dwarfs into special supernovae that help scientists measure the expansion of the universe.
If the theory is confirmed with further work, it would show that stars that died hundreds of millions of years ago may have taken some Earthlings to the grave with them, forever altering the course of life on our world.”
The last supernovas before the universe dies in a heat death will be twice-dead ancient relics on a mind-boggling time scale, according to astrophysicist Matt Caplan.
Your teeth and bones have star stuff.
Scientists have discovered a handful of stars that are inexplicably rich in phosphorus, a key ingredient for life as we know it, in our galaxy.
The half-exploded star is careening across the Milky Way at 900,000 kilometres per hour, according to a new study by international researchers.
Astronomers are trying to figure out whether the star collapsed into a black hole without going supernova, or if it disappeared in a cloud of dust.
The record-smashing explosion in the cosmos was at least twice as bright as the next most luminous supernova ever observed.
The Murchison meteorite, which impacted Australia decades ago, contains astral dust that predates the birth of the Sun.
New observations from a Chilean telescope showed scientists that the Milky Way's core exploded with massive star deaths just one billion years ago, a recent event in cosmic terms.
Scientists didn't even know how to look for this type of black hole until now, thanks to a new study.
