Webb telescope discovers ancient galaxies and mysterious space dust.

The James Webb Space Telescope has discovered the faintest galaxy yet seen in the early universe, known as JD1, which is part of the first generation of galaxies to pop up in our universe's 13.8-billion-year history. It's about 13.3 billion light-years away from us, meaning we're observing it as it looked when the universe was only a few hundred million years old. Astronomers used a technique called gravitational lensing, in which light from a distant object is bent by the gravity of something huge in the foreground, like a cluster of galaxies, to observe JD1.
