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.'
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. “While most galaxies in this era are still small and only gradually growing larger over time,” he said in an email, “there are a few monsters that fast-track to maturity. Why this is the case or how this would work is unknown.”Each of the six objects looks to weigh billions of times more than our sun.

A 500-Meter-Long Asteroid Flew Past Earth, and Astronomers Were WatchingAn asteroid the size of the Empire State Building flew past Earth in early February, coming within 1.8 million km (1.1 million miles) of our planet. Not only is it approximately the same size as the building, but astronomers found the asteroid – named 2011 AG5 — has an unusual shape, with about the same … Continue reading 'A 500-Meter-Long Asteroid Flew Past Earth, and Astronomers Were Watching'
