Bereket Mamo, a graduate student and contractor at Southwest Research Institute, conducts laboratory experiments to simulate hydrogen peroxide production on Jupiter’s icy moon Europa. Scientists ...

NASA engineers have spent the past decade developing a rugged, partially autonomous lander designed to explore Europa, one of Jupiter’s most intriguing moons. The space agency got cold feet over ...

The icy surface of Jupiter's moon Europa appears to be constantly changing, new data from the James Webb Space Telescope has revealed. This phenomena, the team explained, is heightened in so ...

A series of experiments support spectral data recently collected by the James Webb Space Telescope that found evidence that the icy surface of Jupiter's moon Europa is constantly changing ...

Europa’s surface ice is crystallizing at different rates in different places, which could point to a complex mix of external processes and geologic activity affecting the surface.

A camera built at Arizona State University is on its way to check for signs of life above Jupiter, but it detoured to Mars for testing.

NASA’s Europa Clipper spacecraft has completed initial commissioning of its ultraviolet spectrograph (UVS), which will help determine the composition of the atmospheric gases and surface ...

On a mission to discover if one of Jupiter's 4 moons, Europa, supports life, NASA's robotic spacecraft, Clipper, captured a close-range image of Mars.

NASA's Europa Clipper spacecraft captured a thermal image of Mars during a gravity-assist flyby, testing instruments ahead of its mission to explore Jupiter’s ocean moon Europa.

The Space Telescope Science Institute in Baltimore, which operates the Webb and Hubble telescopes, released a video of Jupiter's tempestuous roiling auroras, which you can watch above.

Jupiter's stunning auroras are hundreds of times brighter than those seen on Earth, as pictured in new images taken by the James Webb Space Telescope.

These pictures highlight surface cracks on Mars (top row), the icy crust of Jupiter’s moon Europa (bottom left), and terrestrial analogs on Earth (bottom middle and right).
