"Now, astronomers have found a possible answer: a large group of 12 billion-year-old galaxies almost 90% of which were wreathed in bright gas that — after being ignited by light from the surrounding stars — triggered intense bursts of star formation as the gas cooled. The new research has been accepted for publication  in The Astrophysical Journal.

"Our paper proves that interactions with the neighboring galaxies are responsible for the unusual brightness of early galaxies," lead author Anshu Gupta, an astrophysicist at Curtin University in Australia, told Live Science in an email. "The explosion of star formation triggered by the interactions could also explain the more massive nature of early galaxies."

Astronomers discovered the bright gas clouds in data collected as part of JWST's Advanced Deep Extragalactic Survey, which used three of the telescope's instruments to collect infrared images of galaxies before analyzing their spectra."
