Blue Dwarf Galaxy Located 30 Million Light-Years Away
An astonishing new discovery was recently published in the Astrophysical Journal, where astronomers found a small blue galaxy located 30 million light-years away, which has the smallest fraction of heavy elements ever seen in a galaxy.
Professor John J. Salzer, of Indiana University and senior author of the paper said “Finding the most metal-poor galaxy ever is exciting since it could help contribute to a quantitative test of the Big Bang,” suggesting that the material hasn’t changed much since and that very little star formation has happened.
However, Salzer goes on to explain, “There are relatively few ways to explore conditions at the birth of the universe, but low-metal galaxies are among the most promising.”
This dwarf galaxy is about 1,000 light-years across and made of a few million stars, some of which have been recently formed, causing its blue color and has the lowest luminosity ever observed.
