Webb Telescope Captures Stunning New Views of the Lion Nebula

The James Webb Space Telescope (JWST) has released new images of the Lion Nebula (NGC 2392), showcasing its superior infrared capabilities compared to the Hubble Space Telescope. The images, captured with Webb's Mid-Infrared Instrument (MIRI) and Near-Infrared Camera (NIRCam), reveal unprecedented details of the planetary nebula, including compact clumps of dust and a haze of ionized gas. Hubble's earlier visible-light images from 2000 had a distinctive orange palette that made the nebula appear more lion-like, but Webb's infrared vision provides a sharper and more detailed view. The nebula's structure is shaped by a dying low-mass star at its center, which has shed its outer layers to form shells of gas and dust. The central white dwarf, described as a 'button nose,' illuminates the surrounding material, creating a lion-like appearance with a mane of dust and cometary tails. Scientists note that the nebula is evolving rapidly on a cosmic timescale and may completely disperse within 10,000 years. The images were processed by A. Pagan (STScI) and are credited to NASA, ESA, CSA, and STScI.
