The Mystery Of The Galaxies That Shouldn’t Be There
Astronomers have wondered for decades how long it took for the islands of fiery, sparkling stars, that we call galaxies, to emerge out of the primeval darkness after the Big Bang birth of the Universe almost 14 billion years ago. In May 2017, a team of astronomers announced that they may have solved this nagging cosmic riddle when they discovered a new kind of galaxy haunting the ancient Universe less than a billion years after the Big Bang. These primordial galaxies are seen giving birth to new glittering baby stars more than a hundred times faster than our own Milky Way Galaxy is today. This important discovery could explain a mysterious earlier finding–that a population of surprisingly massive galaxies danced in the Cosmos only 1.5 billion years after its birth.
