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

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

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.

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 ...

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

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 ...

A massive star in the Andromeda Galaxy, one of the most luminous objects in its neighborhood, has quietly disappeared. Over the span of roughly eight years, the star dimmed by more than 10,000 times ...
