NASA's Webb Telescope Exposes Fierce Star Formation In The Lion Nebula
The intrepid James Webb Space Telescope (JWST) has captured a stunning infrared view of a dynamic planetary nebula roughly 4,200 light-years away in the constellation Gemini (NGC 2392), with its latest images revealing intricate dusty filaments and expanding plasma shells.
First discovered in 1787 by astronomer William Herschel and famously imaged in visible light by the Hubble Space Telescope in 2000, NGC 2392 is historically known as the Eskimo Nebula or Clownface Nebula, and more recently as the Lion Nebula. Where Hubble photos showed a glowing, atmospheric ring, Webb’s combined Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) observations cut through the dust to expose the violent mechanics sculpting the system from the inside out.
At the center of NGC 2392 is an oxygen-rich, lower-mass star that ran out of nuclear fuel, and because it was unable to sustain fusion, the dying star began pulsating and shedding its outer layers into...
