ASU Planetarium to Host ‘Dark-Sky Week’ Activities

The Angelo State University Planetarium will host an evening of activities in observance of National Dark-Sky Week Monday, April 20, on the ASU campus.

Activities will consist of a star show in the ASU Planetarium at 8:30 p.m. followed by a “lights out” star party at 9 p.m. in the parking lot of the Vincent Nursing-Physical Science Building, 2333 Vanderventer St. Both events are open free to the public. Participants are encouraged to bring personal telescopes or binoculars to the star party.

National Dark-Sky Week (NDSW) is an annual event in the U.S., during which citizens are encouraged to turn off any unnecessary outdoor lights in order to temporarily reduce light pollution. Light pollution is a hazy blanket of light in the atmosphere caused by improper lighting fixtures that direct light up into the sky instead of down toward the ground. Not only does light pollution waste energy, it also creates great problems for stargazers. According to the NDSW Web site, this “blanket of light” causes the beauty of the night sky to fade and if the problem of light pollution is not addressed now, we are destined to lose the beauty of the cosmos that has been a part of human civilization since its beginning.

National Dark-Sky Week falls annually in the week of the new moon in April, as a full moon actually increases light pollution. This year, it runs from April 20-26.

For more information on Monday’s events, call the ASU Planetarium at 942-2136.
