CMB Maps provides amazing cosmic microwave background all-sky maps for your iPhone and iPad. You can compare different generations of CMB fluctuations with 4K resolution COBE/WMAP/Planck maps. Zoom in, scroll around for details, and tilt your device to compare multiple maps. A sky reference map shows galactic coordinates, Milky Way components, and microwave point sources.

The Cosmic Microwave Background (CMB) is the afterglow radiation from the Big Bang, with uniform temperature and tiny fluctuations. COBE, WMAP, and Planck missions have provided detailed observations, enhancing our understanding of the Universe. Designed by Qingqing Mao at Vanderbilt University, this app is an excellent tool for astronomy education and demonstration.
