NASA’s James Webb telescope spots the oldest “dead” galaxy

The James Webb Space Telescope has recently made an incredible discovery of a “dead” galaxy that stopped forming stars when the universe was only 5% of its current age. This event occurred approximately 13.1 billion years ago, just 700 million years after the Big Bang. This finding is considered to be the earliest instance of a galaxy in a dormant state, surpassing previous discoveries by around 500 million years.

Astrophysicist Tobias Looser from the University of Cambridge’s Kavli Institute for Cosmology led the study published in Nature and compared the galaxy to the late actor James Dean, noting its rapid star formation followed by an abrupt halt. The galaxy, estimated to contain between 100 million and one billion stars, is similar in size to the Small Magellanic Cloud dwarf galaxy near the Milky Way. Unlike the Small Magellanic Cloud, which continues to form new stars, this galaxy has ceased star formation.

Researchers found that the galaxy experienced a brief burst of star formation lasting between 30 to 90 million years before suddenly stopping. Potential reasons for this sudden cessation are currently under investigation, including the influence of a supermassive black hole at the galaxy’s center or energy feedback from newly formed stars. Another possibility is that star formation ended due to a depletion of gas, either through rapid consumption or a lack of replenishment.

The James Webb Space Telescope has provided astronomers with unparalleled views of the early universe since it became operational in 2022. In this study, researchers observed the dormant galaxy at a single moment in time, leaving the possibility open that it may have resumed star formation later on.

In summary, researchers have discovered an ancient “dead” galaxy that stopped forming stars at just 5% of its current age and around 700 million years after
