Become a Citizen Scientist!

Participate in the citizen scientist Globe At Night initiative, sponsored by the National Science Foundation, as a visual observer.
Following five easy steps, using only your eyes, you can make sky measurements that will contribute to a world wide light pollution database used by scientist to map and track global light pollution. The how to is detailed on the Globe At Night website.
In a nutshell, the site provides a series of charts, for each of several selected constellations, corresponding to different levels of light pollution. The darker the sky the more stars you can see in the constellation best position for observing on a given night. By matching the chart to what can be seen an estimate of the light pollution at that place and time can be made and be reported. The side benefit is that over time an observer will learn the night sky’s principal constellations.

Get involved in the 2020 Globe at Night Adopt-a-Street program

Are you passionate about Dark Skies? Consider coordinating an Adopt-a-Street program in your area during the 2020 Globe at Night campaign.

What is the Adopt-a-Street Program?

Globe at Night offers a "Call to Action" for those who want to take more measurements during the campaigns. Children and adults can "Adopt a Street" in their town to take visual and possibly sky-brightness meter measurements during the Globe at Night campaigns. The aim is for people to adopt a different major or semi-major street and take measurements every mile or so for the length of the street (or for as long as they can). The grid of measurements will canvas the town, allowing for research later in comparison to wildlife, health, energy consumption and cost, among other things.

What do I do as the Adopt-a-Street coordinator for my city?

As the Adopt-a-Street coordinator, you will have a couple of responsibilities.

  • In the form provided by Globe at Night, you will need to provide your name and email address for contact purposes and to initiate the process.
  • Next you'll need to look over the instruction text that will appear on your city's Adopt-a-Street web page and make any changes needed for your locale.
  • We will ideally need 25 street names that cover your city in a grid or "spokes on a wheel" formation. (Include as many streets as possible.) These should be main streets, at least a half-mile (1km) apart. For cities that more or less form a grid, choose streets that are parallel to each other (e.g., all streets on your list should be East/West or North/South, but not both).

Once you have provided this information to us, we will create an Adopt-a-Street page for your city, and send you the URL for that web page. Find people in your city to commit to adopting one or more streets by visiting the page and signing up. It's as simple as entering their email address next to the street they wish to cover sometime during the 2020 campaign. Their email remains unseen by others. The street they sign up for simply shows it has been adopted.

How do I recruit people to participate?

Advertise to groups in your area. Potential participants can be found in local amateur astronomy groups, schools, and in groups like the Girl Scouts.
