Globe at Night Program

Background/Talking Points: Light pollution is intrusive artificial (usually outdoor) light. Too much light pollution can wash out starlight, interfere with astronomical research, disrupt ecosystems, and have adverse health effects. Globe at Night is an international citizen science project that involves the public in measuring and collecting night sky brightness observations to help scientists understand the impact of light pollution.

Age group: All ages, children 13 and under will need an adult to help submit data

Event timing and location: The observation should be taken at least one hour after sunset, outdoors, preferably on a moonless night (Check Campaign dates for optimal viewing).

Preparation (one hour):

  1. Review the project protocol: https://scistarter.org/education/Globe-at-night-education
  2. Download and print the data entry sheet.
  3. Consider downloading a free night sky app such as “Night Sky” to locate constellations.
  4. Optional Tools: This project has a corresponding Citizen Science Library Kit (see image to the right). Learn more at SciStarter.org/library-build-a-kit.

Set the Stage

After Sunset

​

Collect Data

One Hour After Sunset

  • Assist participants in finding the right constellation to determine level of light pollution. There are mobile apps for this, like “Night Sky.”
  • If you have the Measuring Light in the Night library kit, help participants use the planisphere to identify constellations and take a light meter reading with the SQM-L.

Tip: Night vision needs to be maintained to find an accurate reading. Use red-light flashlights instead of white light, and avoid phone screens as much as possible during the activity.

Take Action

Program Description

After Observation

  • Introduce participants to practices, behaviors and lighting methods that limit light pollution. Visit DarkSky.org for information on how to take action.
  • Have a discussion about what participants can do to practice these low light and intentional light design methods at home, and in the community.
  • Encourage participants to visit SciStarter.org/darksky for more projects to take action against light pollution.

Programming tips: Make your event a star party by inviting amatuer astronomers to join! Check out NASA’s Night Sky Network to find amateur astronomers in your area. Boost engagement with hands-on STEM activities searchable on STAR Net’s STEM Activity Clearinghouse.

Subject Matter Experts

Light pollution affects many parts of our lives, which means many types of experts can speak to the topic. If the project leader is unavailable, consider speakers on these topics:

  • Astronomers
  • Biologists
  • Medical professionals, sleep experts
  • Energy professionals
  • Local officials who work on resident safety

​

Find these experts locally or through programs like Skype a Scientist or Physicists-to-go.
