For the first time, scientists have made a clear X-ray detection of chlorine and potassium in the wreckage of a star using ...

Berkeley and elsewhere have performed spectroscopic and photometric study of a peculiar supernova designated SN 2021ukt, which underwent a transition from Type IIn to Type Ib. Results of the new study ...

A tale of two supernovae - The beginning of winter is a great time to be taking up astronomy, with long dark nights and a ...

For years, scientists thought they understand what happens when stars explode. New earliest-ever mages of supernova events ...

Some white dwarfs in rapid binary orbits are far hotter and larger than theory predicts. Researchers found that powerful tidal forces between them generate enough heat to inflate their sizes and ...

"Why are we here?" is humanity's most fundamental and persistent question. Tracing the origins of the elements is a direct ...

While walking home on November 11, 1572, astronomer Tycho Brahe idly glanced at the sky. He was surprised to see a bright star in the constellation Cassiopeia that hadn’t been there before. The new ...

Astronomers recognize three flavors of type I supernovae: type Ia, Ib, and Ic. Type Ia supernovae occur in binary systems, where matter from a normal companion star flows onto a white dwarf. The white ...

How much light does a supernova shed on the history of universe? New research by cosmologists at the University of Chicago and Wayne State University confirms the accuracy of Type Ia supernovae in ...

Supernovae – the Earth-shattering ‘kabooms’ – are magnificent stellar displays that provide us with a plethora of useful scientific information about many facets of the universe. They are also ...

Some 2 million years ago, the life of a nearby star ended—not with a whimper, but a bang. Its death—a stellar explosion called a supernova—was so cataclysmic that it sent the star’s innards hurtling ...

Space is a pretty vast place and most of it consists of just that – space. Galaxies tend to be in clusters and stars tend to bunch together into galaxies. Which is why the Universe’s loneliest ...
