Citizen Science Month
Acts of Science: Dark Sky Edition
Celebrate International Dark Sky Week (April 13–20, 2026)
Help reach 2.50 Million Acts of Science in celebration of America’s 250th Birthday!
Calling all International Dark Sky Event Hosts!
This April, SciStarter and partners invite you level up your events with Acts of Science.
What is an Act of Science?
An activity, like sharing an observation of nature, the night sky, or bird migration, that helps scientists fill data gaps.
Why it matters:
Light pollution affects sleep and wildlife. Turn your observations into Acts that help science and make a real difference.
