A hidden ocean lurks beneath Callisto’s icy shell, revealed by a cutting-edge data analysis method. Could this long-overlooked moon rival Europa in the search for extraterrestrial life?
Decades-old Galileo mission data, once obscured by noise, now suggests a vast salty ocean beneath Callisto. A new filtering method has unlocked the moon’s biggest secret yet.
Callisto, often seen as a frozen wasteland, may hold a deep, briny ocean beneath its battered crust. This discovery raises the question: Could alien life thrive in its dark waters?
Europa has long been the favorite for alien oceans, but Callisto’s low radiation and abundant oxygen make it a surprising contender. Could this overlooked moon be a safer haven for life?
NASA’s Galileo spacecraft may have stopped transmitting decades ago, but a new study just extracted fresh insights from its data, revealing a magnetic signature of hidden water.
NASA’s Europa Clipper and ESA’s JUICE mission will soon confirm what Galileo hinted at—Callisto might be the third Jovian moon with an underground ocean. What else will they uncover?
A newly detected magnetic signal suggests that Callisto’s ocean isn’t just water—it’s salty, conductive, and possibly interacting with Jupiter’s magnetic field in ways we never imagined.
Unlike Europa, Callisto orbits farther from Jupiter’s harsh radiation, making it a calmer environment for potential life. Could this mean it’s an even better place to search for habitability?
With Europa Clipper and JUICE arriving in the 2030s, Callisto is finally getting the attention it deserves. The next decade could rewrite what we know about habitability in the outer solar system.
