## CMB Maps Description
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. Check the Wikipedia page for more details: 

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

The included CMB maps are generated by NASA and ESA. COBE, WMAP and sky reference image credits:

## CMB Maps Reviews in United States

### *---- "Can’t be downloaded"
Developer needs to update this app or it needs to be removed from App Store.
-- Gray2025!, 2025-07-07

### ****- "Good app that needs an update"
I’ve enjoyed this app on older IPhones and IPads. However, it needs an update to run on the new operating system. The Contact form doesn’t work so I’m hoping the author will see this. I look forward to using this app again.
-- SF Presidio, 2022-08-26

### ***** "Love it!"
A fantastic for exploring the Universe!
-- ThatgreatHeeyo, 2015-07-17

### ***** "Zoom and fade between 20+ years of CMB data"
Fun tool to look at CMB maps from the 3 major missions. I particularly like the sky reference overlay.
