Astronomers have discovered an enormous structure outside a galaxy hiding in an uncharted region of space far from the center of the Milky Way. that we cannot see, at least with standard visible-light telescopes, is that the Milky Way’s bulging center obscures our view of it; The center of our galaxy is so dense with stars, dust, and other matter, that light from the avoidance zone is scattered or absorbed before reaching Earth’s telescopes..
However, researchers have had better luck revealing the region’s secrets using telescopes that can detect infrared radiation, a type of energy invisible to the human eye, but powerful enough to shine through thick clouds of gas and dust. Evidence for the existence of thousands of individual galaxies shining through cosmic fog, although little is known about the large-scale structures that lie there..
The researchers combined data from several infrared scans to reveal the largest structure ever detected in the avoidance zone, according to a study published October 28 in the preprint database. arXiv.org .
Located about 3 billion light-years from Earth, the mysterious structure appears to be a large group of galaxies linked together by a common center of gravity, using observations from a survey. VVV – A survey studying the Milky Way’s central bulge at infrared wavelengths using the Visible and Infrared Survey Telescope for Astronomy in Chile, study authors found evidence of at least 58 galaxies clustered together in a small piece of the region from the avoidance..
Galaxy clusters are the largest gravitationally bound objects in the universe, and the largest known clusters contain hundreds of thousands of galaxies clustered together, since it is impossible to know how wide or massive a newly discovered cluster is, given the vast distances and the myriad obstacles that exist between the cluster’s stars and the Earth..
However, the mere detection of this huge object shows that the avoidance zone may not be as mysterious as previously thought, and future infrared studies, including possible observations by the James Webb Space Telescope, which has already used its infrared camera. To capture the deepest picture of the universe yet, it should further help scientists unlock the hidden secrets behind the Milky Way..
