Astronomers have obtained remarkably detailed images of two stellar explosions -- called novae -- just days after they began.

New high-resolution images show that novae are anything but simple stellar fireworks. One exploded with multiple gas streams ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

A research team led by Caltech may have just discovered the first-ever superkilonova, a cosmic phenomenon in which a star explodes twice in violently different ways. Their analysis of a series of ...

NASA’s Lucy spacecraft, which is investigating a group of asteroids that share Jupiter's orbit around the sun, snapped this image on September 16 as 3I/ATLAS approached Mars. NASA / Goddard / SwRI / ...

Supernovae aren't one of the JWST's main science themes, but the perceptive telescope is full of surprises. Recently, it pinpointed a single star in a galaxy when the universe was only about 730 ...

NRAO News reports on a new study in which astronomers have detected radio signals from a rare type of stellar explosion for the first time. The discovery was made using the U.S. National Science ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...
