This shimmering cosmic curtain displays interstellar gasoline and dirt that has been heated via the flashbulb explosion of a long-ago supernova. The gasoline then glows infrared mild in what’s referred to as a thermal mild echo. Because the supernova illumination travels thru house on the pace of sunshine, the echo seems to enlarge. NASA’s James Webb Area Telescope noticed this mild echo within the neighborhood of the supernova remnant Cassiopeia A.Credit: NASA, ESA, CSA, STScI, J. Jencson (Caltech/IPAC)
