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

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

A puzzling cosmic blast detected in both light and gravitational waves may hint at a previously unseen type of explosion, ...

A “New Kind of Supernova” with bare-bones chemistry At the heart of the story is SN 2021yfj, a blast that an international collaboration has described as a new kind of supernova whose spectrum looks ...

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

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 ...

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 ...

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 Finch” is a bright flash of light that appeared on many telescopes on April 10, 2023. To this day, astronomers don’t know what set it off. The avian moniker belongs to an event scientists spot ...

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 ...

If the Sun was born in a relatively compact open cluster (half-mass radius ~3pc) with ~10^3 stars, it is quite likely that a massive (>10MSun) star was nearby when it exploded in a supernova. The ...

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 ...
