Gamma ray

Considering the recent history of star birth, star death, and chemical element creation in the Milky Way, the National Aeronautics and Space Administration (NASA) has chosen a new space telescope proposal out of 18 proposals. The new gamma-ray telescope is called Compton Spectrometer and Imager (COSI). The COSI is likely to be launched in 2025. Reportedly, the mission is excepted to cost more than $145 million.
