Astrophysics

Planetary nebula

A compact planetary nebula shown as a small, symmetrical circular to slightly oval expanding shell of semi-transparent ionized gas surrounding a bright tiny central white star. The nebula has a ring-like, hollow, or bubble-like appearance with a darker central cavity, a brighter luminous inner rim, faint layered interior structure, and thin translucent outer halo. The shell is colored mainly in cyan, turquoise, teal, and blue-green, with pink, reddish, violet, or occasional golden filaments along the rim. Outer edges are wispy, misty, and diffuse against an isolated background, conveying a delicate expanding gaseous envelope. Render in clean scientific clipart style with soft diffuse glow, crisp edges, and moderate detail.
