NASA’s New High Resolution Map of Galaxies Might Help Understand ‘Dark Matter’

NASA has shared a new high resolution map of galaxies, which could help to comprehend ‘Dark Matter’. According to international reports, dark matter is a strange form of substance that holds galaxies together. NASA scientists created the most complete map of dark matter to date using earlier results and fresh data from the James Webb Space Telescope (JWST). The intricate effect of the map on the structure of the universe has been described.

The image above is primarily a depiction of over 800,000 galaxies, which are overlaid with a map of dark matter, which is represented in blue. Researchers utilized data from Webb to discover the undetectable substance by observing how its gravity affected normal matter, according to NASA.

The study, which was released in Nature Astronomy on January 26, demonstrates the overlap between dark matter and ordinary matter and emphasizes how it affects the formation of galaxies and galaxy clusters. The research was carried out in partnership with Durham University, NASA’s Jet Propulsion Laboratory (JPL) and the Ecole Polytechnique Federal de Lausanne (EPFL) in Switzerland.

‘Dark matter’ is believed to have unusual qualities, such as being undetectable, because it does not interact with light, unlike regular stuff. It is believed that dark matter makes up about 85% of all the material in the Universe that was produced during the Big Bang.

The map displays the web like a structure of dark matter, with thick knots around galaxy clusters and finer threads connecting them. It is hypothesized that gravity from dark matter brought gas and dust closer to it, resulting in the circumstances necessary for the formation of galaxies.
