CMB Maps

Amazing cosmic microwave background all-sky maps on your iPhone and iPad!

This app allows you to see and compare different generations of CMB fluctuations. It includes 4K resolution all-sky COBE/WMAP/Planck CMB maps and allows you to zoom in and scroll around for map details. You can choose to view a single map, or compare multiple maps by tilting your device. A sky reference map is also included to show the galactic coordinates, notable Milky Way components, and microwave point sources.

Cosmic Microwave Background (CMB) is the afterglow radiation from the Big Bang. Its temperature is extremely uniform, but with tiny fluctuations as you will see in these maps. 

In 1992, COBE satellite made the first detection of the CMB fluctuations. The following WMAP and Planck mission were able to scan the sky at better and better resolution. The successes of these CMB observations have provided us great understanding of the Universe over the last decades.

This app is designed and made by Qingqing Mao at Vanderbilt University for the purposes of astronomy education and demonstration.
