Almost everywhere we find water on Earth, we also find life. So water’s presence or absence is an initial way to assess a world’s habitability. As it happens, Earth’s planetary neighbors may have once been wetter. For as long as 2 billion years, liquid water may have covered much of the surface of Venus. But today Venus is a hellscape. The planet’s...
Around most stars is a region where conditions are just right for an orbiting planet to have liquid water on its surface. That region is the star’s habitable zone or "Goldilocks zone.” But scientists have learned that worlds outside the Goldilocks zone can have liquid oceans as well, including several moons in our outer solar system. Some moons of ...
The outer solar system contains several ocean worlds. Among them are two of Europa’s neighbors. Scientists think Jupiter’s moons Ganymede and Callisto have oceans, sandwiched between layers of ice. High-energy particles around Jupiter generate chemical compounds on the moons’ surfaces that living things might find useful. But the outer ice shell of...
Pioneer 10 kicked things off. The spacecraft flew by Jupiter in 1973 and performed the first survey of the planet and its moons. In 1979, Voyager 2 captured the first close images of Europa, to reveal ridges and cracks on the moon’s surface. It also showed us that Europa might be geologically active today. From 1995 to 2003, the Galileo spacecraft ...
Does Europa harbor life? As yet, we have no evidence for life at Europa, but… Between 50 and 80 percent of life on Earth is in the ocean. Not only plants, coral, fish, and mammals, but also extremophiles — organisms that survive in extreme environments. They live in freezing realms below arctic sea ice and in the boiling temperatures and crushing p...
Learn how Europa, one of Jupiter's moons, may have liquid water and the ingredients for life beneath its icy surface. Explore the history, science, and exploration of this ocean world and its neighbors in the outer solar system.
14 oct. 2024 · Europa Clipper is the first NASA mission dedicated to studying an ocean world beyond Earth, with the goal of determining whether it has conditions that could support life. The spacecraft launched on Oct. 14, 2024, and will fly by Mars and Earth before reaching Jupiter in 2030.
13 oct. 2024 · Learn about the mission to explore Europa, a possible habitat for life, with 49 flybys and nine science instruments. Find out the launch date, time, and details, and watch a video overview.
6 févr. 2024 · Learn about Europa, Jupiter's icy moon with a possible liquid water ocean beneath its surface. Find out how NASA's Europa Clipper spacecraft will survey Europa to search for signs of life in 2024.
