After four years of relentless day-and-night efforts, four Bengali scientists have finally achieved success in their research, surprising the entire world with their groundbreaking discovery. Scientists from a remote district of West Bengal have revealed giant radio galaxies in the universe, which are several times larger than other galaxies. This discovery was highly praised by other scientists around the globe. The discovery was made almost entirely using indigenous technology.
The scientists mentioned that the dark corners of the universe still hide countless unknown cosmic objects that have yet to be discovered and are invisible to the naked eye. One such object is the Giant Radio Source (GRS) galaxies. These ancient, gigantic galaxies cannot be seen easily. These objects can be spotted only using radiowaves and wavelengths. Through these radio waves, 34 ancient giant galaxies have been identified by scientists. This discovery will surely be a significant development in the field of space science.
As per reports, for around four years, a team of Bengali astronomers has been on an unknown journey that led them to discover these 34 new giant radio galaxies. The researchers used 30 special radio telescopes at the National Centre for Radio Astrophysics (NCRA) of the Tata Institute of Fundamental Research (TIFR), located near Khodad village, around 90 km north of Pune. The telescopes used are known as the Giant Metrewave Radio Telescope (GMRT), each having a diameter of 45 m.
The team of Indian astronomers, led by Professor Sabyasachi Pal, the head of the Department of Pure and Applied Science at Medinipur City College, made this amazing discovery using the TGSS radio sky map. The team also include PhD researchers Souvik Manik and Nitai Bhakta with Susanta Kumar Mondal, an assistant professor of physics at Sidho-Kanho-Birsha University in Purulia.
Professor and scientist Sabyasachi Pal said, “These colossal radio galaxies in the universe usually are of huge sizes. Their sizes are equivalent to 20-25 Milky Way galaxies. By analysing the radio waves emitted from these massive galaxies, we were able to make this discovery after four years of hard work.”
