Overview
- Images from the James Webb Space Telescope were released on Monday, Aug. 10, 2026, showing NGC 2392 with far finer infrared detail than prior visible-light views.
- Webb’s NIRCam and MIRI data expose compact dust clumps, a bubble of ionized gas that makes the “face,” and comet-like filaments that form the nebula’s mane.
- The new images show both dust destruction by the hot central white dwarf and surviving dense filaments, giving direct clues about how radiation reshapes expelled stellar material.
- Scientists are using the mid-infrared signatures to probe the nebula’s dust chemistry and dynamics, search for possible embedded star-forming pockets, and plan targeted follow-up observations.
- The release, processed by STScI (image credit Alyssa Pagan) updates the Hubble-era view, highlights Webb’s dust-penetrating power, and clarifies that NGC 2392 is one of two objects sometimes called the “Lion Nebula.”
