Cosmic microwave background

A flat 2D scientific false-color map of the cosmic microwave background shown as an all-sky heatmap, typically in an oval full-sky projection but sometimes presented as a circular disk or rectangular map. The entire field is filled with smooth, softly blurred, speckled mottling that represents tiny temperature anisotropies, with irregular patches and blobs in warm reds, oranges, and yellows contrasted with cooler blues, dark blues, greens, cyan, pale yellow, and occasional white. The background appears diffuse and uniform overall, with no stars, labels, or foreground objects, resembling a clean cosmology temperature map of ancient microwave radiation. Style note: flat 2D clipart rendering with soft gradients, minimal detail, and no outlines.
