EPIC Observations of Ice in Earth's Atmosphere

The Discover satellite captures sparkling glints of light from Earth, caused by sunlight reflecting off ice particles. This phenomenon was first observed by the Galileo spacecraft in 1990. Studying these glints helps understand light reflection and its impact on Earth's radiation budget. This method could also be used to identify ice crystals in exoplanet atmospheres, aiding in evaluating their habitability.
