The supernova was likely to be a red supergiant It was hidden behind Abell 370 galaxy cluster The first image was taken just six hours after the explosion Space enthusiasts have been fascinated by ...

The cataclysmic event sent sent particles of gas and dust shooting into space at speeds up to 100 million kilometers per second. The explosion also was annotated by something quite unexpected: Instead ...

For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

While we know that all the Sun and the lineup of planets would have been accumulated over time from a dense cloud of gas where gravity allowed all of it to clump together, we weren’t entirely sure if ...

A massive supernova explosion that destroyed a faraway star apparently turned the left over stellar corpse inside out as well, scientists say. Using NASA's Chandra X-ray Observatory spacecraft, a team ...

A supernova explosion first seen from Earth 436 years ago has come back to life for astronomers in a time-travel-like astronomical twist. By observing light from supernova SN 1572 that was slowed on ...
