James Webb Space Telescope discovers candidates for most distant galaxies yet

Astronomers have spotted what may be the two most distant galaxies ever seen hiding in early-release images from NASA’s newest space telescope.

The James Webb Space Telescope‘s early science work includes a program called the Grism Lens-Amplified Survey from Space, or GLASS. Through GLASS, astronomers are scrutinizing the galaxy cluster Abell 2744, which is so massive that its gravity is able to distort the space around it and act as a gravitational lens to magnify the images of far more distant galaxies behind it.
