A plume of water vapor and ice spurts from cracks at the south pole of Saturn’s moon Enceladus at a rate of about 200 pounds (100 kilograms) per second, hinting at a subsurface sea.
Observing the plasma, or hot ionized gas, spurting from these same openings may lead to insights about how sunlight and plasma interact to influence magnetic fields.
The face of the moon is illuminated by light reflected off Saturn in this April 29 photo captured from 483,000 miles (777,000 kilometers) away by NASA’s Cassini spacecraft.
