Red dual opposing jets coming from young stars fill the darker top half of the image. At bottom center is a glowing pale yellow, cave-like structure, its top tilted toward two o’clock, with a bright star at its center. The dust of the cave structure becomes wispy toward eight o’clock. Above the arched top of the dust cave, 3 groupings of stars with diffraction spikes are arranged. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. The dark shadow of the cloud appears pinched in the center, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the cloud. The largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges. At top center, a star displays another, larger pinched dark shadow, this time vertically. To the left of this star is a more wispy, indistinct region.
