We’re celebrating International Dark-Sky Week with an image from a corner of New Mexico that’s one of the best places to stargaze in the continental United States. Dark-Sky Week is observed during the first new moon of April, when stars shine more brightly because the moon isn’t visible. The event was created to bring attention to the harmful effects of artificial light on the natural world, and to remind us of the beauty of an unadulterated night sky. Light pollution not only impacts our ability to see the stars and to sleep soundly, but also creates challenges for many nocturnal species, migrating birds, and even baby sea turtles. So, turn out those lights, look up, and be amazed at the sky that your great-great-grandparents saw.
