New high-resolution images of the Fomalhaut A system from the NASA/ESA/CSA James Webb Space Telescope show three debris belts extending out to 23 billion km (14 billion miles) from the star. The scale of the outermost belt is roughly twice the scale of our Solar System’s Kuiper belt. The inner belts — which had never been seen before — were revealed by Webb for the first time. This image, taken with Webb’s Mid-Infrared Instrument (MIRI),...

This Hubble image shows eMACS J1823.1+7822, a massive cluster of galaxies some 9 billion light-years away in the constellation of Draco. The central cluster is mostly made of bright elliptical galaxies that are surrounded by a warm glow. Close to the cluster core is the stretched, distorted arc of a galaxy, gravitationally lensed by the cluster. Image credit: NASA / ESA / Hubble / H. Ebeling.
