"Uncovering a Galactic Fossil: Insights into Universe's Evolution"
NASA scientists have discovered a cosmic fossil created by a supermassive black hole eruption over 5 million years ago in the spiral galaxy NGC 4945. Using the XMM-Newton space telescope, they observed X-rays outlining cold gas clouds, providing insight into how supermassive black holes influence their surroundings and guide galactic evolution. The galaxy, undergoing intense star formation, exhibits features of an active galactic nucleus, and the team theorizes that the black hole's eruption triggered this starburst period. Further observations will focus on understanding the black hole's influence on the galaxy's evolution and its potential role in quenching star formation.
