ALT Infographic titled “Motions of Gas Around an Extremely Red Quasar.” On the left is a Hubble image of a field of galaxies, with one central galaxy spotlighted. On the right is a zoomed-in, multicolor image of that same galaxy, newly revealed by Webb to be part of a galaxy cluster. Four single-color images, taken by Webb in various wavelengths, make up the multicolor image and can be found in more detail at the bottom of the graphic. These images show light from the gas (doubly ionized oxygen atoms) in the galaxy cluster. A color code explains that color represents the motion of the gas, including direction and speed relative to the quasar. From left to right: the first image (blue) shows gas moving toward us at 350 kilometers per second; the second (green) shows gas steady in our line of sight at 0 kilometers per second; the third (orange) shows gas moving away at 370 kilometers per second; the fourth (red) also shows gas moving away, but at 700 kilometers per second.
