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. A new study from NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) confirms that one particular ULX, called M82 X-2, is definitely too bright. The neutron star consumes around 1.5 Earths' worth of material each year, siphoning it off of a neighboring star, and 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.
