English: Presented here as a World Map, the CMB features are named after continents and seas, with labels drawn from the constellations below. The concave, double-hemisphere map resembles two halves of an empty orange peel. For reference, the Milky Way’s plane runs along the equator, with the center positioned at the heart of the image. The blue and brown colors indicate temperature fluctuations of up to 300 µK around a 2.725 K average. Although these fluctuations are extremely subtle, the most prominent differences occur on a physical scale of about one degree—roughly 1/180th of the sphere’s diameter—appearing as small dots across the full circle. This results in numerous small islands and fragmented bodies of water. Data credit: ESA and Planck Collaboration. Map idea and realization by Pablo C. Budassi in May 2025.
