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. Good thing we’ll only need one telescope to spot incredible stellar nurseries in faraway galaxies — but we may need a couple of eyepieces, so we’re exploring a few recent innovations and how to select the best ones for your observing needs. 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.
