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

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 Gamma-ray spacecraft has observed a super-bright, supercharged supernova explosion powered up by the creation of ...

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

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

A supernova is one of the most powerful events that can happen in the Universe - we are talking, after all, about a star exploding – and because of that, they have always been actively researched by ...
