Europa, the icy moon around Jupiter, boasts a remarkable feat: it produces 1,000 tons of oxygen daily. This astounding oxygen production from Europa can fulfill the breathing needs of a million people for 24 hours.
Scientists studying Jupiter’s moon Europa have uncovered a surprising revelation: the icy celestial body generates a significant amount of oxygen. This discovery, detailed in a recent study published in Nature Astronomy, sheds new light on the moon’s potential to support life.
NASA’s Juno mission researchers have determined the rate at which Europa produces oxygen. Using data collected by the spacecraft’s instruments, scientists calculated that Europa generates approximately 26 pounds of oxygen every second.
Scientists have long puzzled over the production in question, with earlier studies offering varying estimates. However, recent calculations by NASA’s Juno mission indicate a significantly lower oxygen production rate than previously thought, challenging existing theories.
Europa’s potential for harboring life
Beneath Europa’s icy exterior lies a vast ocean, raising intriguing questions about the moon’s potential for harboring life. Scientists speculate that oxygen produced on the surface may seep into Europa’s subsurface ocean, serving as a potential energy source for microbial life.
Europa’s unique position within Jupiter’s radiation belts makes it a hotspot for astrobiological investigation. Bombarded by charged particles from the gas giant, Europa’s icy surface undergoes processes that generate oxygen, hinting at the possibility of life-supporting conditions below its frozen crust.
Europa resembles an ice ball gradually releasing its water into a flowing stream. However, in this scenario, the stream consists of ionized particles carried by Jupiter’s remarkable magnetic field, according to JADE scientist Jamey Szalay from Princeton University.
“When these ionized particles impact Europa, they break up the water-ice molecule by molecule on the surface to produce hydrogen and oxygen. In a way, the entire ice shell is being continuously eroded by waves of charged particles washing up upon it,” said Szalay.
Clipper mission in 2030
NASA says the Europa Clipper mission will explore various aspects, including oxygen production when it reaches Jupiter in 2030. The mission is equipped with nine advanced scientific instruments to verify whether Europa harbors conditions suitable to life.
