Lion Nebula Roars to Life With NASA’s Webb

August 10, 2026

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

July 29, 2026

$A rectangular image with thousands of galaxies of various shapes and colors on the black background of space. Some are noticeably spirals, either face-on or edge-on, while others are blobby ellipticals. Many are too small to discern any structure. One prominent foreground star at top center features Webb’s signature 8-point diffraction spikes. At upper right, a box shows a zoomed in portion of the image. The pullout features a spiral galaxy labeled “WISEA J123635.56+621424.2.” The galaxy has a bright yellow center and faint brown arms speckled with regions of blue that appear to wind clockwise around the galaxy’s core.$
