It's the last clearly observed supernova in the Milky Way, Gassel said.

The blast may have been a kilonova — a type of neutron star merger — in the wake of a more traditional supernova.

The space agency pieced together the evolution of Kepler’s Supernova Remnant from the data of NASA’s Chandra X-ray ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed ...

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, ...

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, while the Zwicky Transient Facility was the first to detect light from the ...

Some 350 years after a supernova, its shockwave reaches interstellar space and causes clouds of gas and dust to glow. Scientists have probed the remains of a star that died in a violent supernova and ...

It’s challenging to make predictions, especially in astronomy. There are however, a few forecasts astronomers can depend on, such as the timing of upcoming lunar and solar eclipses and the clockwork ...

Isotope ratios found in meteorites suggest that a supernova exploded nearby while the Sun and Solar System were still forming. But the blast wave from a supernova that close could have potentially ...

Astronomers are winding back the clock on the expanding remains of a nearby, exploded star. By using NASA’s Hubble Space Telescope, they retraced the speedy shrapnel from the blast to calculate a more ...
