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 is these elements that sustain such galaxies as they grow, helping to shape them into the familiar ellipses and spirals we see across the cosmos.
