Scientists working with material collected from asteroid Bennu have found a sticky, gum-like organic substance never before ...

Once charted as a 'guest star' in ancient China, dreaded as a harbinger of ill omens in medieval Europe, and preserved in the ...

NASA's Fermi Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of a highly magnetic dead star, or magnetar.

An international team analyzed data from NASA's Fermi space telescope and detected gamma rays from a rare and exceptionally ...

Brutal. The post Astronomers Say Star Self-Destructed So Catastrophically That It Left Behind No Trace of Its Existence ...

Earth is quietly collecting radioactive debris from an ancient stellar explosion as our Solar System drifts through a giant cloud of gas and dust between the stars. Scientists analyzing Antarctic ice ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

Researchers leverage a multiangle simulations approach to elucidate the roles of neutrino fast flavor conversion affects core ...

Is a star about to explode in the night sky? If predictions come true, T Coronae Borealis (T CrB) could become visible for a ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...
