ALT These shimmering cosmic curtains show interstellar gas and dust that has been heated by the flashbulb explosion of a long-ago supernova. The gas then glows infrared light in what is known as a thermal light echo. As the supernova illumination travels through space at the speed of light, the echo appears to expand. NASA’s James Webb Space Telescope observed this light echo in the vicinity of the supernova remnant Cassiopeia A. NASA, ESA, CSA, STScI, J. Jencson (Caltech/IPAC)

ALT At the center is a thin horizontal pinkish cloud known as Herbig-Haro 211 that is uneven with rounded ends, and tilted from bottom left to top right. It takes up about two-thirds of the length of this angle, but is thinner and longer at the opposite angle. At its center is a dark spot. On either side of the dark spot, there are orangish yellow wisps that extend to light blue wisps. Within the center of those clouds, a pink fluffy streak runs through each lobe. At the ends of each lobe, pink becomes the dominant color. The lobe to the left is fatter. The right lobe is thinner, and ends in a smaller pink semi-circle. Just off the edge of this lobe is a slightly smaller pink semicircle, then a pink sponge-like blog. The background contains several bright stars, each with eight diffraction spikes extending out from the central bright point. Credits: ESA/Webb, NASA, CSA, T.
