Webb Telescope: What will scientists learn?

The James Webb Space Telescope's first images aren't just breathtaking—they contain a wealth of scientific insights and clues that researchers are eager to pursue.
Here are some of the things scientists now hope to learn.
Into the deep
Webb's first image, released Monday, delivered the deepest and sharpest infrared image of the distant universe so far, "Webb's First Deep Field."
The white circles and ellipses are from the galaxy cluster in the foreground called SMACS 0723, as it appeared more than 4.6 billion years ago—roughly when our Sun formed too.
The reddish arcs are from light from ancient galaxies that has traveled more than 13 billion years, bending around the foreground cluster, which acts as a gravitational lens.
