Can You See the Stars?
Join thousands of other students, families and citizen-scientists hunting for stars from Monday, February 25, through Saturday, March 8. Take part in this international event called GLOBE at Night to observe the nighttime sky and learn more about light pollution around the world.

GLOBE at Night is an easy observation and reporting activity that takes approximately 15-30 minutes to complete. Citizen-scientists record the brightness of the night sky by matching its appearance toward the constellation Orion with 1 of 7 stellar maps of different limiting magnitude. They then submit measurements online at www.globe.gov/globeatnight/ .
Resulting maps of all observations are created and placed back online by the GLOBE at Night staff within the few weeks that follow.

The five easy star-hunting steps, for which more information is provided online, are:

  1. Find your latitude and longitude.
  2. Find Orion by going outside an hour after sunset (about 7-10pm local time)
  3. Match your nighttime sky to one of our magnitude charts.
  4. Report your observation on our website. (Observations can be made February 25 through March 8; you may report through March 15).
  5. Compare your observation to thousands around the world.

Helpful and user-friendly ancillary materials such as a teacher packet and science standards, a family packet, and student games and information are provided online at:

During the inaugural event in 2006 over 18,000 people from 96 countries submitted 4600 observations, including data from every U.S. state. In 2007, the number of observations almost doubled. Help us exceed 10,000 observations in 2008!
