Webb Reveals Hidden Dust and Gas Structures in the Lion Nebula

Webb’s infrared images let scientists trace how a central white dwarf sculpts dust and ionized gas inside NGC 2392.

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.”
