COSI is a balloon-borne soft gamma-ray (0.2-5 MeV) telescope designed to study astrophysical sources of nuclear line emission and gamma-ray polarization. Learn more by reading about the Science behind COSI, its Design and related Publications.

The COSI Team launched the instrument from Wanaka, New Zealand, in May 2016 aboard a Super Pressure Balloon.  Learn about the work in their Blog PostsTwitter FeedFacebook Wall, or in the News.
