Europa's Buried Ocean: Galileo’s Point Sparks a Vast Subsurface Sea

From Galileo's 1610 sighting of a tiny moon near Jupiter, scientists now consider Europa to host a global salty ocean buried under kilometers of ice, potentially larger than Earth's oceans. Magnetic data and surface geology suggest a 60–150 km-deep ocean under a 15–25 km ice shell, but no direct samples exist yet. NASA's Europa Clipper will study the ice shell, ocean, and chemistry to assess habitability without drilling through the ice or directly seeking life.

Europa plume claims lose steam after reanalysis

A 14-year reanalysis of Hubble data casts doubt on Europa’s previously claimed water vapor plumes, lowering confidence from about 99.9% to under 90% and suggesting the earlier detections may have been due to data placement noise; the team says plumes can’t be ruled out, but the question may be settled by NASA’s Europa Clipper mission expected to arrive in 2030.

Europa plumes under doubt as reanalysis lowers confidence

A fresh reanalysis of 14 years of Hubble data weakens the case for intermittent water vapor plumes on Jupiter’s moon Europa, reducing certainty from 99.9% to below 90% and leaving open the possibility that plumes exist but not yet definitively confirmed; future missions like Europa Clipper are expected to settle the question.

Ammonia clues on Europa rekindle hunt for a habitable ocean

A new look at Galileo data detected faint ammonia near Europa’s fractures, implying a subsurface ocean or ammonia-laden shallow layers and boosting the case for habitability; the upcoming Europa Clipper mission will continue to search for chemical signs of life.

Track Four Legendary Probes Across January’s Night Sky

Space.com guides readers to spot four legendary spacecraft—James Webb Space Telescope (JWST), Europa Clipper, JUICE, and Voyager 1—in January’s night sky, with finder charts and timing tips (including JWST’s path from Orion toward Jupiter and the planet’s January opposition). The piece also suggests using timeanddate or stargazing apps (Starry Night, Stellarium) for precise rise/set times and locations, and adds bonus targets around Orion’s Belt and the Orion Nebula.

Mysterious Spider-Like Formations on Europa and Jupiter Spark Alien Life Theories

Scientists have proposed that the mysterious spider-like feature observed on Europa's surface, initially thought to be a structure within a crater, may have formed through processes similar to Earth's lake stars, but likely resulted from an asteroid impact that created cracks allowing salty water to seep through, providing insights into Europa's subsurface and potential signs of extraterrestrial life.

NASA's Europa Clipper Radar Excels During Mars Flyby

NASA's Europa Clipper spacecraft tested its radar during a flyby of Mars, using the planet's proximity to calibrate instruments ahead of its 2030 mission to Europa. The successful test involved bouncing radio waves off Mars and collecting data, helping scientists prepare for detailed studies of Europa's icy shell, composition, and structure. The spacecraft, launched in October 2024, aims to explore whether Europa's environment could support life.
