Urgently Wanted—Star Counters

Through March 8, an organization known as GLOBE at Night is asking for help tallying celestial bodies in the constellation Orion. Designed as a teaching aid, this star-counting program aims to emphasize the loss-of-darkness throughout the globe, a problem which hinders ground-based astronomy. Students, families, and the general public can report their results online by […]
