Using the James Webb Space Telescope, astronomers have made a new observation of what they say is the oldest galaxy seen to have stopped forming stars.
Using the James Webb Space Telescope, astronomers have made a new observation of what they say is the oldest galaxy seen to have stopped forming stars.
An international team of astronomers has spotted a so-called “dead” galaxy that stopped forming new stars just 700 million years after the Big Bang.
“Galaxies need a rich supply of gas to form new stars, and the early universe was like an all-you-can-eat buffet,” he added.
The astronomers determined that the galaxy had a “short and intense burst star formation” that stopped between 10 and 20 million years before the point in time it was observed with the James Webb Space Telescope.
But now that we can see so much further back in time, and observe that the star formation was quenched so rapidly in this galaxy, models based on the modern universe may need to be revisited,” he added.
This is one of the deepest observations made with the James Webb telescope, the astronomers said and used data from the JADES (JWST Advanced Deep Extragalactic Survey).
