Astrophysicists are trying to wrap their heads around another twist in the story of fast radio bursts – mysterious radio frequency emissions that reach us from distant galaxies. Magnetars rotate slowly compared to other neutron stars, so scientists reasoned that it is the objects’ ultra-strong magnetic energy rather than their rotation that probably produces the emission of FRBs. This was …
An enigmatic celestial object that is so bright that it should have burst has left researchers puzzled. The analysis confirmed that one ultraluminous X-ray light called M82 X-2 can be 10 million times as bright as the sun. M82 X-2 pulled in about 9 billion trillion tons of material per year from a neighbouring star, or about 1.5 times the …
CNN — A mysterious astronomical object merged with a black hole 780 million light-years away and created gravitational waves that could be detected on Earth. The object exists inside what scientists call the “mass gap,” a range between the heaviest known neutron star and the lightest known black hole. “Mergers of a mixed nature — black holes and neutron stars …
