BEIJING, Dec. 2 (Xinhua) — NASA has discovered a supermassive black hole that has been breeding stars at a “crazy rate” and can produce an average of 500 stars a year, the Daily Mail of London reported.
The latest observation swarm of Phoenix stars is shown, with 500 stars a year, while the Milky Way breeds only one star a year.
Researchers at the Massachusetts Institute of Technology (MIT) used the Chandra X-ray Observatory and the Hubble Space Telescope to target a distant cluster of galaxies called the Phoenix Cluster, which contains a supermassive black hole that is ideal for the birth of a star.
Unlike supermassive black holes found in the center of other galaxies, black holes found inside the Phoenix cluster are weaker, and gas clouds inside the galaxy are easily cooled and begin to breed stars, a phenomenon that astronomers have long been looking forward to finding.
For decades, NASA has been searching for a breeding hotbed of stars at the center of the galaxy( the region closest to the supermassive black hole in the galaxy), but has not yet been found. In previously observed galaxies, the superheated gas flowing around the center of the galaxy was cooled by X-ray exposure, but then reheated by a burst of radiant energy from the center of the supermassive black hole, disrupting the star-forming process, the researchers said.
Imagine turning on air conditioning in your hot summer home, but then lighting firewood so that your bedroom doesn’t cool down unless it goes out, as does the gas cool down when the black hole’s heating capacity is turned off.
The star-bearing effect in the Phoenix cluster is remarkable, with about 500 stars a year, compared with just one star a year in the Milky Way. (Ye Ding Cheng)
