Opis: Are we looking at the future of our Sun? The James Webb Space Telescope captured todayâs composite image of the Lionâs Head Nebula (NGC 2392) with its NIRCam and MIRI instruments. The Lionâs Head Nebula is the remnant of a Sun-like star. This star was unable to sustain the nuclear fusion in its core needed to remain stable. It began to shed layers of gas and dust into space, forming this planetary nebula. A hot stellar core, called a white dwarf, is left behind within the lionâs nose. Do not boop this nose! Intense radiation from the white dwarf is ionizing the gas as it expands, creating the irregular bubble that makes up the lionâs face. Dust clumps that have survived the white dwarfâs radiation and a cloud of ionized gas make up the lionâs mane. This new and more detailed view of the nebula will help humanity learn more about how the gas and dust interact with each other and the white dwarf radiation.
