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

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

A new video shows the evolution of Kepler's Supernova Remnant using data from NASA's Chandra X-ray Observatory captured over ...

NASA has captured 25 years of observations from the Chandra X-ray Observatory showing the aftermath of Kepler’s Supernova, a ...

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

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

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 ...

A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...

Hypervelocity stars (HVS) are celestial bodies moving at speeds sufficient to escape the Milky Way's gravitational pull, with a primary proposed origin involving binary star interactions with the ...

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 ...

The Ursa Major Arc is about 600 light years away and encircles the Big Dipper (part of Ursa Major the Great Bear), and portions of the Little Dipper, Draco and Canes Venatici. The faint arc requires ...

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 ...
