Compton Spectrometer and Imager (COSI)

Class:

Flight Project

Status:

Under Study

Organizations:

COSI would scan our Milky Way galaxy, measuring gamma rays from radioactive elements produced during stellar explosions to map the recent history of star death and element production. It would also measure polarization, to improve our understanding of how distant energetic cosmic explosions produce gamma rays.
