Why It Matters
These moments of alignment, known as eclipses, occultations, and transits, allow scientists to study distant objects in remarkable ways.
Key Details
- By observing how light changes when an object briefly blocks another, astronomers can measure sizes and shapes, detect atmospheres, and refine the orbits of asteroids and planets.
- From left to right: Image of the total solar eclipse of 2024, an asteroid occulting a distant star, and an exoplanet transiting a star.
- The Science Through Shadows project, funded by NASA’s Science Activation program and led by Fiske Planetarium at the University of Colorado Boulder, explores how these shadow-based events help scientists conduct astronomical research.
- The project has produced a series of short films that explain the science behind eclipses, occultations, and solar observations while highlighting the people who help make these discoveries possible – including students, educators, and volunteer citizen scientists.
