Scientists have revealed for the first time a jaw-dropping early view of an exploding supernova. Observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed ...

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

A dying massive star does not go quietly. Its core collapses, matter crashes inward, neutrinos pour out in staggering numbers ...

But one massive star, hundreds of times heavier than our Sun, self-destructed so catastrophically that it left behind no ...

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

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 ...

NASA’s Fermi telescope may have finally uncovered the magnetic powerhouse behind the universe’s brightest supernovae.

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 ...

A faint, ancient flash of light detected by the James Webb Space Telescope (JWST) has broken the record for the most distant stellar explosion ever recorded, revealing a massive star’s demise when the ...

Through the years since it was first launched, the Hubble Space Telescope has captured stunning photographs of the Cassiopeia ...

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 ...
