Star clusters are of great importance in any galaxy: they are the birthplace of new stars, often containing massive stars of 10 solar masses or more. Such massive stars often drive powerful winds; the ...

A massive star in the Andromeda Galaxy, one of the most luminous objects in its neighborhood, has quietly disappeared. Over the span of roughly eight years, the star dimmed by more than 10,000 times ...

Distant galaxies that abruptly stopped making stars have puzzled astronomers for years. About 9 billion years ago, during one ...

Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

WASHINGTON, April 3 (Reuters) - A supernova - the explosive death of a star - is always violent, blasting material into space while typically leaving behind a compact stellar remnant like a neutron ...

Were massive stars in the early universe born in pairs? A new study from the School of Physics and Astronomy at Tel Aviv University reveals that most massive stars formed in the early universe were ...

Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be examples of dark stars. The concept of dark stars has existed for some ...

High in the Milky Way, a dying giant has thrown astronomers a cosmic curveball. A star known as DFK 52, sitting in the massive Stephenson 2 cluster about 19,000 light-years away, has been caught ...
