More than 30,000 celestial images that were all but lost to science are about to find their way back into researchers’ hands thanks to the efforts of thousands of citizen scientists. The photographs, radio maps, and other telescopic images were scanned from the pages of dusty old journals for a cosmic reclamation project called Astronomy Rewind. Its goal is to bring these “zombie” images back to life so that astronomers can find them online and compare them with modern electronic data from ground- and space-based telescopes, making possible new studies of short- and long-term changes in the heavens.
