Fight for Dark Skies, Explore May's Moon, and More
Wander outside this balmy spring and take a closer look at the Moon. Even if you're peering through the haze of light pollution (the worthy topic of our cover story), you might be surprised by the detail you can see with your naked eye, especially if you follow Alan MacRobert's guide in this issue. Then go deeper with author Andrew Livingston, who chronicles lunar features as they were named by Giambattista Riccioli - a fascinating history with perhaps a secret agenda. Another take on history comes from Mary Alexandra Agner's visit to the Harvard College Observatory. The institution's century-old plate collection, which unveils long-term changes in the night sky, is contributing in novel ways to modern research. You'll find all that and much more in the May issue.
