New Universe Map Unveils Around 300,000 Unidentified Galaxies

Our chart of the universe is extending: An international astronomers group just found 300,000 unidentified galaxies within space. Over 200 astronomers from eighteen nations published the foremost stage of a new radio sky survey utilizing the LOFAR (Low Frequency Array) telescope, as said in a press release by the Netherlands Institute for Radio Astronomy (ASTRON). The researchers—that published their discoveries in the Astronomy & Astrophysics journal—stated this finding may assist the astronomers to study more relating to the black holes’ physics and how huddles of galaxies develop.

Radio astronomy reveals the processes of the universe that cannot be observed with optical instruments by humans. For this astronomy study, the LOFAR telescope scrutinized at low-radio frequencies around 25% of the northern hemisphere. Approximately 10% of this information is public and it charts 300,000 unnoticed light resources that are deemed to be distant galaxies within the universe.

Utilizing the LOFAR telescope located in the Netherlands, the researchers identified “jets” of very old radiation produced when galaxies fuse together. These hints—that were earlier unidentified to astronomers, can generate radio emission that covers millions of light-years. After these examinations, the researchers utilized a high-throughput compute cluster and information gathered from the LOFAR telescope to produce a high-quality map picture.

In the press release, Amanda Wilber from the University of Hamburg, Germany, stated, “With radio examinations, we can identify radiation from the vague medium that subsists between galaxies. The radiation is produced by turbulence and energetic shocks. LOFAR enables us to notice many more of these resources and comprehend what is powering them.”

Likewise, recently, astronomers examining a globular star cluster inadvertently found a more-distant galaxy beyond it. The small galaxy is around 30 Million light-years far-off and is dubbed Bedin 1. The researchers discovered this small galaxy while utilizing the Hubble Space Telescope to picture the globular star cluster.
