Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the Big Bang, suggesting the early universe may have had a stellar fast-track that produced these “monsters.”
This image provided by NASA and the European Space Agency shows images of six candidate massive galaxies, seen 500-800 million years after the Big Bang. One of the sources could contain as many stars as our present-day Milky Way, but is 30 times more compact.
While the new James Webb Space Telescope has spotted even older galaxies, dating to within a mere 300 million years of the beginning of the universe, it’s the size and maturity of these six apparent mega-galaxies that stun scientists. They reported their findings Wednesday.Lead researcher Ivo Labbe of Australia’s Swinburne University of Technology and his team expected to find little baby galaxies this close to the dawn of the universe — not these whoppers.
“The revelation that massive galaxy formation began extremely early in the history of the universe upends what many of us had thought was settled science,” Leja said in a statement. “It turns out we found something so unexpected it actually creates problems for science. It calls the whole picture of early galaxy formation into question.”
Unlike Hubble, the bigger and more powerful Webb can peer through clouds of dust with its infrared vision and discover galaxies previously unseen. Scientists hope to eventually observe the first stars and galaxies formed following the creation of the universe 13.8 billion years ago.
