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 ...

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 telescope captured near-infrared light from one of the earliest stars seen to explode in the history of the universe.

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 ...
