Greater Phoenix City Nature Challenge 2026: Acts of Science – Connected − Comets, Clues, and Our Cosmic Story
Help NASA-supported scientists find active comets to find clues about our early universe.
All you need is curiosity.
Featured Project: Rubin Comet Catchers
During this virtual event, you’ll look through real images from the Vera C. Rubin Observatory to find comets and other active objects in our solar system. Each comet you spot offers valuable clues about how planetary systems form and evolve, and the possible origins of Earth’s water.
Hear from the project scientist, ask questions, and discover how your participation supports important research AND counts towards a goal of 2.50 Million Acts of Science this April (Citizen Science Month!).
