(ORDO NEWS) — A team of researchers from the National University of San Juan, the Federal University of Rio Grande do Sul and the Andrés Bello University have found evidence of a large extragalactic cluster lurking behind the Milky Way galaxy.
A group of scientists published a paper describing their findings on the arXiv preprint server. The study is awaiting publication in the journal Astronomy & Astrophysics.
Scientists have long known that one part of the night sky is hidden from our eyes due to a bulge in the galaxy. The zone of avoidance is approximately 10% of the night sky.
Over the past few years, scientists have used various tools to study this area.
The experts started the new study by analyzing the data that has been collected so far and adding new information obtained through the VVV Survey project.
The VVV Survey is a project sponsored by the European Organization for Astronomical Research in the Southern Hemisphere.
The research involved studying stars using infrared radiation rather than visible light.
Such ejecta are capable of passing through gas, dust and light from stars in the bulge and onto instruments installed here on Earth.
By studying infrared images, the researchers were able to identify several galaxies that exist far beyond the Milky Way.
The researchers believe that together these galaxies make up a massive extragalactic structure. They estimate that there could be up to 58 galaxies in this structure.
