Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: Are we looking at the future of our Sun? The James Webb Space Telescope captured today's composite image of the Lion's Head Nebula (NGC 2392) with its NIRCam and MIRI instruments. The Lion's 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 lion's 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 lion's face. Dust clumps that have survived the white dwarf's radiation and a cloud of ionized gas make up the lion's mane. This new and more detailed view
