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

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

A strange flash in a distant galaxy first looked like a familiar kind of stellar wreckage, the radioactive afterglow of ...

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

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

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, ...

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 ...

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 ...

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 ...

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 ...
