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, ...

A strange cosmic blast that lit up the sky in two distinct acts is forcing astronomers to rethink how stars live and die. The event, tagged AT2025ulz, appears to be the first known case where a ...

The combination of a supernova and a kilonova may have produced a rare space explosion that astronomers have never seen ...

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

A mysterious cosmic explosion linked to gravitational waves may reveal a previously unknown type of supernova event - a ...

When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the ...

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 ...

A supernova from the early universe looks unexpectedly familiar, challenging ideas about how the first massive stars lived ...

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 ...

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 ...
