New Delhi: Astronomers have discovered a new galaxy called as ``fossil galaxy`` which is believed to be a left over from the early universe.
Named as Segue 1, it is the faintest galaxy ever detected. It has a very small size and contains only about 1,000 stars. Also, Segue 1 has a rare chemical composition, with vanishingly small amounts of metallic elements present.
The astronomers also found telling evidence in the lack of so-called "neutron-capture elements"-those found in the bottom half of the periodic table, which are created in intermediate-mass stars.
The findings on Segue 1 also indicate that there may be a greater diversity of evolutionary pathways among galaxies in the early universe than had been thought.
Astronomers suggest that the study of galaxies such as Segue 1 is a vital part of progress to learn more about the Big Bang theory and unravel the histories of the Milky Way and other nearby galaxies.
The study has been published by the journal Astrophysical Journal.
