Facts about Europa's Possible Biosphere
- 08
Chloride salts detected in Europa's plumes by the Hubble Space Telescope in 2013 suggest the subsurface ocean has a composition similar to Earth's oceans, supporting habitability for potential microbial life.
- 07
Sulfur and oxygen compounds detected in Europa's plumes by the James Webb Space Telescope indicate chemical disequilibrium that could power metabolic processes for potential subsurface organisms.
- 06
Europa's water plumes eject material up to 200 kilometers into space, offering the NASA missions a direct sampling method without drilling through kilometers of ice.
- 05
Tidal heating from Jupiter's gravity generates approximately 10 watts per square meter of internal warmth within Europa, potentially sustaining chemosynthetic life in the subsurface ocean.
- 04
Jupiter's radiation belts expose Europa's surface to approximately 540 rems of radiation annually, potentially creating chemical energy through radiolysis that could sustain subsurface microbial ecosystems.
- 03
Organic molecules detected by the Hubble Space Telescope in Europa's water plumes suggest carbon-based chemistry necessary for life exists in the moon's subsurface environment.
- 02
Hydrothermal vents on Europa's seafloor could provide chemical energy sources similar to Earth's deep-sea ecosystems, potentially supporting chemosynthetic organisms.
- 01
Beneath Europa's 10-kilometer ice shell, a subsurface ocean contains more water than all Earth's oceans combined, potentially harboring microbial life.
