Speck of light glimpsed by Hubble is truly an enormous old galaxy, James Webb Space Telescope reveals


What was little more than a speck of light for the Hubble Space Telescope has been revealed as one of the oldest galaxies ever discovered — and the finding owes itself to none other than Hubble’s younger sibling: The James Webb Space Telescope.

The James Webb Space Telescope international “Glass” Collaboration made detailed observations of the galaxy, dubbed Gz9p3, which is seen as it was just 510 million years after the Big Bang. That’s during the relative infancy of the universe, which is now 13.8 billion years old.
