Exploring Ionized Gas in Our Galaxy
The Wisconsin H-Alpha Mapper (WHAM) is an astronomical observatory tailored to study wide-spread, diffuse optical emission from the Milky Way. Here at our site you can find an overview of the project, its specialized Fabry-Perot spectrometer, and more techincal detail about the installation. Then, explore the science we've been doing, or download our publicly released Hα survey. Finally, delve into WHAM-related publications and presentations that discuss our discoveries and results in more detail.
WHAM was built and operates due to support primarily from the National Science Foundation.
