Astronomers have found a giant "extragalactic structure" concealed behind the Milky Way, according to a new study published in Arxiv.
The discovery of the structure, which appears to be a colossal galaxy cluster, contributes to filling in this mysterious region of our cosmic map, known as the "zone of avoidance." Nobody has known what exists in this region which obscures 10 to 20 percent of the sky- until now.
The study explained that the zone of avoidance (ZOA) does not allow clear optical observations of extragalactic sources behind the Milky Way. The research paper describes the reason for this being an "extinction of the optical emission of these objects." This means that most extraterrestrial structures within the ZOA are hidden, or unobservable.
