Saltwater Similar to the Earth’s Oceans has been Seen on Europa. Another Good Reason Why We Really Need to Visit This Place

Jupiter’s moon Europa is an intriguing world. It’s the smoothest body in the Solar System, and the sixth-largest moon in the Solar System, though it’s the smallest of the four Galilean moons. Most intriguing of all is Europa’s subsurface ocean and the potential for habitability. The scientific consensus is that Europa has a subsurface ocean …

This is What the Ground Looked Like After InSight Landed on Mars

When InSight landed on Mars on Nov. 26th, 2018, it deployed a parachute to slow its descent through the thin Martian atmosphere. As it approached the surface, it fired its retro rocket to slow it even more, and then gently touched down on the surface. As it did so, its retro rockets excavated two small …

Ceres is a Strange Place, Including a Volcanic Peak 4,000 Meters High Made From Bubbling Salt Water, Mud and Rock

Ceres, at almost 1,000 km (620 miles) in diameter, is the largest body in the asteroid belt. Between 2015 and 2018, NASA’s ion-powered Dawn spacecraft visited the dwarf planet, looking for clues to help us understand how our Solar System formed. Ceres is the first dwarf planet ever visited by a spacecraft. Now that scientists …

Mimas Pushes Through Saturn’s Rings Like a Snowplow

Saturn’s moon Mimas is the smallest of the gas giant’s major moons. (Saturn has 62 moons, but some of them are tiny moonlets less than 1 km in diameter.) Two new studies show how Mimas acted as a kind of snow-plow, widening the Cassini division between Saturn’s rings. Saturn’s iconic rings set it apart from …
