Young stars periodically shoot out supersonic jets that collide with clouds of material, like these thick pillars. This sometimes also results in bow shocks, which can form wavy patterns like a boat does as it moves through water. The crimson glow comes from the energetic hydrogen molecules that result from jets and shocks. This is evident in the second and third pillars from the top–the NIRCam image is practically pulsing with their activity. These young stars are estimated to be only a few hundred thousand years old. NASA now anticipates a trove of insights about the universe for the next twenty years. Follow its movements with NASA’s tracker, Where is Webb?
