NASA’s Juno probe will peer beneath the icy crust of Europa

On Sept. 29, NASA’s Juno probe will perform the closest flyby of Jupiter’s icy moon Europa in over 20 years as the spacecraft embarks on a mission to deep probe into Europa’s ice in search of pockets of liquid water. Europe contains a global ocean beneath a solid crust of ice, making this moon one … Read more

A Swarm of Swimming Robots to Search for Life Under the Ice on Europa

When Galileo pointed his telescope at Jupiter 400 years ago, he saw three blobs of light around the giant planet, which he at first thought were fixed stars. He kept looking, and eventually, he spotted a fourth blob and noticed the blobs were moving. Galileo’s discovery of objects orbiting something other than Earth—which we call … Read more

Jupiter’s icy moon Europa to block out star for skywatchers

Later this month, skywatchers in Africa can watch a star blink out of sight thanks to a quirk of celestial arrangements. The European Space Agency (ESA) mission Gaia, which launched in 2013, has been a powerhouse of observational astronomy, making a wide impact on the way scientists study the sky. From mapping the galaxy in … Read more

NASA’s Europa Clipper Mission completes the main body of the spacecraft

Shallow Pockets of Water Under the ice on Europa Could Bring Life Close to its Surface

Beneath the surface of Jupiter’s icy moon Europa, there’s an ocean up to 100 km (62 mi) deep that has two to three times the volume of every ocean on Earth combined. Even more exciting is how this ocean is subject to hydrothermal activity, which means it may have all the necessary ingredients for life. … Read more
