A team of scientists using the European Space Agency's XMM-Newton space telescope have discovered a weird dead star , which hides one of the strongest magnetic fields in the Universe.
Gamma-ray bursts are the most powerful (and mysterious) explosions in the universe, shooting massive concentrated jets of hot plasma that are way too powerful to come from an ordinary supernova. And they might be the birth pangs of black holes.
Pulsars, or neutron stars, are the universe's densest objects other than black holes. Special pulsars known as magnetars can have intense magnetic fields up to a trillion times stronger than our Sun...but one strange magnetar has been hiding its powers.
A star went supernova with more than twice the mass needed to ultimately collapse into a black hole. But something weirder happened - the star became a magnetar, an asteroid-sized star with the most powerful magnetic field in the universe.
A very rare kind of undead star 30,000 light years away caught astronomers' attention this month by vomiting up masses of x-rays and gamma rays so rapidly that it shocked researchers.
