Black hole with glowing accretion disk and measurement scale

A black hole is rendered with a brilliant white-gray accretion disk spiraling inward against deep black space. Centered cross-hairs and measurement scales frame the spherical event horizon at the composition's core.

This exact black hole with luminous accretion disk centered on deep space backdrop, starfield, photorealistic scientific visualization, pristine pure black void background, dramatic side-lit rings glowing white-hot.
