Astrophysics

Ergosphere

An oblate, nonspherical shell surrounding a rotating black hole, shaped like a flattened spheroid or teardrop-like zone that bulges at the equator and narrows toward the poles. Depict it as a semi-transparent glowing region, bluish, violet, amber, or blue-gray, with a smooth outer boundary and a clear circular inner opening representing the separate event horizon region. The shell should read as a distinct rotating zone outside the black hole, wider around the equator than at the poles. Use clean vector-style linework, soft glow shading, and a restrained cool-toned palette.
