Sky & Telescope May 2021 Magazine
In the May 2021 issue of Sky & Telescope, we’re discussing the hunt for cosmic rays and the massive telescope and detector arrays trying to track down their sources.

However, even the best eyepieces won’t help us find life on other planets unless we know what we’re looking for. Astrobiologists are looking for chemical compounds that could signal life if found in the atmospheres of other planets.
