NASA's Astronomy Picture of the Day
2026-09-21 | Cocoon Nebula Wide Field
When does a nebula look like a comet? In this crowded starfield covering over two degrees within the high-flying constellation of the Swan (Cygnus), the eye is drawn to the Cocoon Nebula. A compact star forming region, the cosmic Cocoon punctuates a nebula bright in emission and reflection on the lower right, with a long trail of interstellar dust clouds to the left, making the entire complex appear a bit like a comet. Cataloged as IC 5146, the central bright head of the nebula spans about 10 light years, while the dark dusty tail spans nearly 100 light years. Both are located about 2,500 light years away. A bright star near the colorful nebula's center likely supplies power and helps clear out a cavity. The long dusty filaments of the tail, although dark in this visible light image, hide stars in the process of formation. The featured image was captured in July from Death Valley, California, USA.
