"The universe's early galaxies were less chaotic and developed much faster than previously thought, according to new research looking back more than ten billion years in time. An international team of astronomers led by Durham University, UK, has used the James Webb Space Telescope (JWST) to find evidence of bar formation when the universe was only a few billion years old.
This latest research is published in the journal Monthly Notices of the Royal Astronomical Society.
Bars are elongated strips of stars found in disk or spiral galaxies like our Milky Way. As bars develop, they regulate star formation within a galaxy, pushing gas into the galaxy's central region, and their presence tells scientists that galaxies have entered a settled, mature phase.
Previous studies carried out using the Hubble Space Telescope had been able to detect bar forming galaxies up to eight or nine billion years ago. But the increased sensitivity and wavelength range offered by the JWST means researchers have been able to see the phenomenon happening even further back in time. This means that scientists might have to rethink their theories about galaxy evolution in the early stages of the universe's formation."
