NASA discovers mysterious object 10 million times brighter than the sun.

Ultraluminous X-ray sources (ULXs) are breaking the laws of physics by emitting about 10 million times more energy than the sun, which exceeds the Eddington limit. NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) confirmed that one particular ULX, called M82 X-2, is definitely too bright. M82 X-2 is a neutron star that consumes around 1.5 Earths' worth of material each year, siphoning it off of a neighboring star. The research team thinks that the intense magnetic field of the neutron star changes the shape of its atoms, allowing the star to stick together even as it gets brighter and brighter.
