A key mystery about Type Ia supernovas is that, in the dominant theory known as D6, a white dwarf would need a companion star in order to explode. This so-called D6 scenario is shorthand for ...

A new AI-powered tool has reduced astronomers' workload by 85%—filtering through thousands of data alerts to identify the few genuine signals caused by supernovae (powerful explosions from dying stars ...

Most stars in the Milky Way move at steady speeds, orbiting the galactic center in regular paths. But astronomers have uncovered rare stars so fast they can escape the galaxy’s gravity altogether.

Astronomers once struggled to measure the true size of the universe. Then came the discovery of Type Ia supernovae — explosions so consistent in brightness they could serve as “standard candles.” By ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

It's a scene that could evoke popular fantasy stories, with sparkling stars shining above misty mountaintops, but the James Webb Space Telescope image you see above is of a very real part of our ...

Astronomers use simulations to discover how globular clusters form and reveal a new type of star system near the Milky Way.

The NASA Interstellar Mapping and Acceleration Probe (IMAP) spacecraft is scheduled to launch on September 23, 2025, to study ...

The observatory’s work is far from trivial. It captures gamma-ray, X-ray, ultraviolet, and optical data in real time, studying black holes, supernovae, neutron stars, and other cosmic phenomena.

Researchers from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences have revealed for the first ...

Chain restaurants are often ties to memories and fun occasions with friends and family. These nostalgic restaurants are ...
