NEW YORK: Recently, scientists have discovered some new clues about the formation of the galaxies. The 13.8 billion years old universe is the abode of about 100 billion galaxies, composed of stars, gas and dust. But the researchers do not know of a surety how these clusters came into existence. For capturing light from the early universe, the European Space Agency’s Planck telescope usually used cosmic microwave background signals and created a map of the radiation left by the Big Bang. As time went by, the Herschel telescope was used to zoom in on some of the clusters which were captured by the Planck telescope. This assisted the researchers to examine the precursors of galaxies.
The lead author of the study Hervé Dole said “Finding so many intensely star-forming, dust galaxies in such concentrated groups was a huge surprise. We think this is a missing piece of cosmological structure formation.” NASA further explained that stars and galaxies were abundant in the early universe and they possibly collapsed under the weight of gravity, triggering the creation of new stars and galaxies.
