  "account": "On January 5, 2023, the NASA/ESA/CSA James Webb Space Telescope captured the clearest image yet of the NGC 2392 nebula, also known as the Lion Nebula. This nebula earned its name due to its distinctive appearance resembling a lion's face when viewed head-on.\n\nPrior to this infrared observation, the Hubble Space Telescope had already captured snapshots of the nebula in 2000, highlighting its population of hazy, comet-shaped objects. To create this remarkable image, Webb utilized its Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), which combined data to produce an unprecedented level of detail.\n\nThe image reveals the complex structure of the nebula, featuring the white dwarf at its center, which continues to shape the nebula. This stellar remnant was formed when the progenitor star reached the end of its life cycle and shed its outer layers, leading to the creation of the intricate rings and shells visible in the image.\n\nThe central star is exceptionally hot, causing it to illuminate everything within the bubble, ionize hydrogen, and expand and destroy much of the dust it encounters. Unlike more massive stars that collapse at the end of their lives in a supernova, lower-mass stars like the one responsible for NGC 2392 create nebulae through the process of pulsating and blowing off their outer layers.\n\nAs the hot remnant drives gas expansion and dust clearing, the nebula's lionlike morphology is expected to disperse within about 10,000 years. This ongoing process of shaping and dispersal will continue to alter the nebula's appearance over time.",
