Indian astronomers have discovered a <\/span>Faint Galaxy named <\/b>UVIT J2022<\/b> that remained hidden until now.\u00a0<\/span><\/p>\n Faint Galaxies are <\/span>called low surface brightness galaxies or ultra-diffuse galaxies and have a surface brightness that is at least ten times fainter than the surrounding night sky.\u00a0<\/span><\/p>\n Such faint galaxies may account for up to 15 % of the mass of the universe. However, they are difficult to detect because of their inherent low luminosities.<\/span><\/p>\n It is a faint galaxy. It was discovered while studying a known galaxy, NGC6902A. <\/span>This faint galaxy is in the Milky Way’s neighbourhood situated 136 million light-years away.<\/span><\/p>\n It <\/span>remained undetected because it lay in front of a much brighter galaxy that is further away. <\/span>Moreover, it is extremely faint – about ten times fainter than the surrounding night sky.<\/span><\/p>\n Firstly, <\/b>this study raises the possibility that there could be similar diffuse galaxies that have been wrongly interpreted as interacting galaxies due to their superposition with foreground or background galaxies.<\/span><\/p>\n Secondly,<\/b> t<\/span>he material that the humans see around is known as <\/span>baryonic matter. <\/b>Studies suggest that baryonic matter makes up 5% of the Universe’s mass. The rest of the mass should be contributed by unknown forms such as dark matter and dark energy.<\/span><\/p>\n — However, humans still do not have a clear understanding about the 5% of the baryonic content present in the Universe. These faint galaxies can act as a link for understanding the origin of missing baryons in the universe, as they may contribute significantly to the baryonic mass in the universe.<\/span><\/p>\n Source: <\/b>This post is based on the article <\/span>\u201c<\/b>Hidden in Plain Sight: faint galaxy discovered in our local universe<\/b>\u201d <\/b>published in<\/span> PIB <\/b>on 1st April 2022.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":" What is the News?
