Lion Nebula Roars to Life With NASA’s Webb

$JWST’s Near Infrared Camera and Mid Infrared Instrument combined image of planetary nebula NGC 2392, the Lion Nebula, against the black background of space. The nebula is in the center, circular in shape, and looks like a male lion’s head. In the center is a small, pinkish-white circle with eight-point diffraction spikes, a white dwarf star. Surrounding the star are purple-pink cavernous bubbles and shell-like rings. The bubbles and shells collectively form an oval with two small, wide arcs near the top, reminiscent of a lion’s face and its ears. What appears to be extended outward from the lion’s face is a thick ring of purple-blue material. The area closest to the lion’s face looks cloudy, while the edges of the mane look like there are clumps of dust with comet-like tails and strands. In the background are distant galaxies and stars. Some galaxies are small yellow and orange points of light and others have spiral structures.$
