James Webb Space Telescope spots 3 of our universe’s earliest galaxies

Astronomers using the James Webb Space Telescope have found what they say are three of our universe’s earliest galaxies, spotted actively forming when the cosmos was just 400 million to 600 million years old. In the JWST’s images, this galactic trio resembles fuzzy red smudges feeding on nearby helium and hydrogen.Over millions of years, it […]
