Astronomers Capture Images of Diffuse Gas Strands of Mysterious Cosmic Web
In a breakthrough revolution, it has happened for the first time in the history of astronomical science that researchers have discovered a distant quasar illuminating a vast nebula of diffuse gas.
Cosmologists claimed that the matter inside the universe is arranged into a gigantic web-like structure called cosmic web. They have found large, luminous strands of gas stretched over distance of about two million light-years across intergalactic space.
Researchers have been successful in capturing images of mysterious cosmic web by using 10-meter Keck I telescope at the W.M. Keck Observatory in Hawaii. The research, which has been published in the Journal Nature, states that galaxies are cocooned within gigantic and wispy filaments of gas.
Galaxies are generally believed to move randomly inside the universe but researchers say it does not happen in reality. Galaxies are found in groups, which combine to form clusters.
Astronomers claimed that there exists some force that continues to pull visible matter into the cosmic web. They found that an emission of hydrogen gas illuminated by quasar leads to an emission of ultraviolet light, Lyman alpha radiation.
Sebastiano Cantalupo, from the University of California in Santa Cruz, said: "In this case, we were lucky that the flashlight is pointing right at the cosmic web, making some of its gas glow".
