About 11.5 billion years ago, a distant star roughly 530 times larger than our sun died in a cataclysmic explosion that blew its outer layers of gas into the surrounding cosmos, a supernova documented by astronomers in blow-by-blow detail. Researchers on Wednesday said NASA’s Hubble Space Telescope managed to capture three separate images spanning a […]

The aftermath of a large star’s explosive death is seen in an image released on Monday by the European Southern Observatory, showing immense filaments of brightly shining gas that was blasted into space during the supernova. Before exploding at the end of its life cycle, the star is believed to have had a mass at […]

Sometimes it is hard to remember that we and everyone we know live on a rock that is rapidly moving across an endless and mysterious place that we still know very little about—space. From a gamma-ray burst sweeping across our planet due to the birth of a star to how some stars give a “warning” […]

Astronomers from the Liverpool John Moores University (LJMU) and the University of Montpellier have created an “early warning” system that can alert astronomers when a massive star is about to end its life in supernova explosion. In the last phase of their lives, these massive “red supergiant” stars will become around a hundred times fainter. […]

Last week, we were reminded that spaceflight is still hard when Jeff Bezos-owned Blue Origin’s rocket crashed back to Earth shortly after launch. Fortunately, no one was aboard the spacecraft and nobody was injured during the mishap. Read more about the crash and other interesting news on our weekly space news recap. Blue Origin rocket […]

Astronomers studying the remains of a supernova captured using NASA telescopes have found clues that can help determine the timeline of the star’s demise. Called SNR 0519-69.0, the supernova remnant is the debris from an explosion of a white dwarf star. According to NASA’s Chandra Ray Observatory, the star underwent a thermonuclear explosion after reaching […]
