NASA Discovers Cosmic Object That Challenges Laws of Physics with Its Brightness

NASA's Nuclear Spectroscopic Telephone Array (NuSTAR) has confirmed that ultra-luminous x-ray sources (ULXs) exceed the Eddington limit, which restricts how bright an object can be based on its mass, by up to 500 times. Astronomers believe that the brightness of ULXs is due to magnetic fields so strong that they cannot be replicated in a lab. The ULX designated M82 X-2, which is ten million times brighter than the Sun, is a neutron star that may produce light from gases and dust being smashed into its surface at millions of miles per hour.
