Stephan's Quintet has let us watch faraway galaxies interact

The image of five galaxies, called Stephan's Quintet, is the largest of JWST's subjects to date, covering about a fifth of our Moon's diameter.

There is much going on in this cluster of colliding galaxies, from individual bright young stars, the blazing light emitted by hydrogen falling onto a black hole in one galaxy to the faint glow of dust between the interacting systems. In the corners of the image are countless other smaller and more distant galaxies.
