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.

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 ...

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 ...

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 ...

In 2017, astronomers found hypervelocity stars believed to have come from the Large Magellanic Cloud, supposedly kicked out of binary systems by supernovae. What kept the surviving star from being ...

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 ...

WASHINGTON, June 28 (Reuters) - Astronomers have observed in a relatively nearby galaxy a star that not only survived what ordinarily should have been certain death - a stellar explosion called a ...

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 ...
