Juno Flyby Reveals Stunning New Image of Europa

This look at the complex, ice-covered surface of Europa came from Juno during a close pass on September 29, 2022. The spacecraft had only a two-hour window to collect it, racing past the moon with a relative velocity of about 23.6 km per second (14.7 miles per second).

Phosphorus in the form of orthophosphate (e.g., HPO4-2) is likely abundant in the subsurface ocean of Saturn’s moon Enceladus; a soda or alkaline ocean (containing NaHCO3 and/or Na2CO3) inside of Enceladus interacts geochemically with a rocky core; modeling indicates that this interaction promotes the dissolution of phosphate minerals, making orthophosphate readily available to possible life in the ocean; because phosphorus is an essential ingredient for life, this finding bolsters mounting evidence for habitability within this small Saturnian moon.
