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 ...

The expansion of Kepler's Supernova Remnant over the past 25 years is summed up in 40 seconds in a new video released by NASA. The stunning time-lapse was created using data from 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.

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, ...

The final stage of a superkilonova. Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, ...

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 ...

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 ...
