An Astronaut from NASA has represented the Deepest X-Ray image of Space during the winter assembly of the American Astronomical Society. The snaps taken by NASA’s Chandra X-Ray Observatory are believed to be the deepest-ever X-ray image ever made. The images are collected by the Chandra X-ray Observatory of NASA during 102 pointing sessions held from 1999 to 2016. The x-ray snaps are giving 7-million-second exposure of a piece of the sky which is around two-thirds of the mass of the full Moon. Surprisingly, most dots spotted in the image are supermassive black holes, traced at the cores of galaxies, situated billions of light-years away from the earth.
The image, known as the Chandra Deep Field South was presented on 5th January 2017 by Neil Brandt from the Pennsylvania State University. The picture reveals 1,008 separate sources, each of which is found to be discharging powerful X-rays with energies ranging between 500 and 8,000 electron volts (0.5–8 keV). As said by the scientists of NASA, the picture is an incredible creation of the observatory system of the US-based space agency. The faintest sources that are detected through this image is the existence of clusters of supermassive black holes, which Chandra clicked only one X-ray photon every 10 days.
In the picture, most of the black holes were normally untraceable; especially the distant ones located at a far-flung position from the early universe. The scientists of NASA took 11.5 weeks to completely observe the objects in the photo. The picture, containing a wealth of data has paved a golden path for the astronauts to get significant clues not just about the history and origin of black holes, but about the cosmos itself. The picture also suggests that supermassive black holes may be sowed with the dimensions of 10,000 to 100,000 times more than the mass of our Sun, rather than ‘only 100 times.’
The deepest-ever X-Ray image is now expected to help astronauts to explain the mysterious growth of the black holes. In addition, X-rays from very remote galaxies, located around 12.5 billion light-years away from the earth might help scientist to get clues to the developments of both super-giant and stellar-mass black holes at the initial ears of the universe.
