NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant. Tiny clumps represented in bright pink and orange make up the supernova’s inner shell, and are comprised of sulfur, oxygen, argon, and neon from the star itself. A large, striated blob at the bottom right corner of the image, nicknamed Baby Cas A, is one of the few light echoes visible NIRCam’s field of view. In this image, red, green, and blue…

NASA’s Nancy Grace Roman Space Telescope team is exploring ways to support community efforts that will prepare for the deluge of data the mission will return. Recently selected infrastructure teams will serve a vital role in the preliminary work by creating simulations, scouting the skies with other telescopes, calibrating Roman’s components, and much more. Their work will complement additional efforts by other teams and individuals around the world, who will join forces to maximize Roman’s scientific potential. The goal is to ensure that, when the mission launches by May 2027,…
