NASA Reveals Secret of Ultra-Luminous X-Ray Sources Beyond Eddington Limit

Ultra-luminous X-ray sources (ULXs) produce about 10 million times more energy than the Sun, regularly exceeding the Eddington limit by 100 to 500 times. A recent study published in The Astrophysical Journal utilized NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) to measure a ULX for the first time. Findings confirm that ULXs do indeed break the Eddington limit, potentially due to their strong magnetic fields.
