Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the Big Bang
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.
Each of the six objects looks to weigh billions of times more than our sun. In one of them, the total weight of all its stars may be as much as 100 billion times greater than our sun, according to the scientists, whoLabbe said he and his team didn’t think the results were real at first — that there couldn’t be galaxies as mature as our own Milky Way so early in time — and they still need to be confirmed.
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.
