Researchers have identified a black hole with the help of NASA’s Chandra X-ray Observatory. This blackhole is found in a galaxy named Mrk 462. It is 200000 times the mass of the Sun. Mrk 462 is a dwarf galaxy containing several hundred million stars. In comparison, there are several hundred billion stars in our galaxy. This blackhole, located at a distance of 110 million light years, was hidden in the Mrk 462 galaxy due to the high amount of gas and dust.
a blog by nasa Post It is said that for the first time an ‘obscure’ supermassive black hole has been found in a dwarf galaxy. Astronomers often detect black holes by looking for the rapid motion of stars at the center of galaxies, but existing instruments make dwarf galaxies appear much smaller and fainter. It is difficult to find anything in them. Astronomers use another technique to detect black holes. For this reason this blackhole has been discovered.
Jack Parker of Dartmouth College in New Hampshire, along with his colleague Ryan Hickox, led the research. Jack Parker said that in Mrk 462 it was the smallest black hole of its kind. Hickox said that it was difficult to detect black holes buried in dust and gas, hence the discovery of the existence of many more such black hole dwarf galaxies. may indicate. He said the discovery could help astronomers figure out why black holes in the universe grew so quickly.
Chandra X-ray Observatory was used to observe 8 dwarf galaxies in this study. In these galaxies there were signs of the development of the first black holes. Of them, only the growing black hole was detected in the Mrk 462 galaxy.
Recently, NASA also observed a total solar eclipse from space. Shown Was. The agency shared on Instagram pictures taken from a space observatory, in which the moon’s shadow was seen passing over Antarctica. The Deep Space Climate Observatory (DSCOVR) spacecraft captured the shadow as it passed over Antarctica.
