The James Webb Space Telescope (JWST) has uncovered an old galaxy that lived fast and died young. The telescope conducted the deepest observation to detect this oldest dead galaxy.

This kind of galaxy is extremely rare.The telescope conducted the deepest observation to detect this oldest “dead” galaxy. Astronomers at the University of Cambridge refer to it as a dead galaxy since star production stopped in the blink of cosmic time.
This mysterious galaxy went from actively star-forming to quenched states considerably faster than expected. “The first few hundred million years of the universe was a very active phase, with lots of gas clouds collapsing to form new stars,” said Tobias Looser, the paper’s first author from the Kavli Institute for Cosmology.
