NASA Study Suggests Shallow Lakes in Europa’s Icy Crust Could Erupt

New research makes hypotheses that NASA’s Europa Clipper can test: Any plumes or volcanic activity at the Jovian moon’s surface are caused by shallow lakes in its icy crust. In the search for life beyond Earth, subsurface bodies of water in our outer solar system are some of the most important targets. That’s why NASA […]

NASA’s Juno Shares First Image From Flyby of Jupiter’s Moon Europa

NASA’s Juno Shares First Image From Flyby of Jupiter’s Moon Europa

Observations from the spacecraft’s pass of the moon provided the first close-up in over two decades of this ocean world, resulting in remarkable imagery and unique science. The first picture NASA’s Juno spacecraft took as it flew by Jupiter’s ice-encrusted moon Europa has arrived on Earth. Revealing surface features in a region near the moon’s […]

NASA’s Juno Will Perform Close Flyby of Jupiter’s Icy Moon Europa

NASA’s Juno Will Perform Close Flyby of Jupiter’s Icy Moon Europa

As the spacecraft makes a close approach of the moon, it is expected to provide valuable science – and remarkable imagery – for NASA’s upcoming Europa Clipper mission. On Thursday, Sept. 29, at 2:36 a.m. PDT (5:36 a.m. EDT), NASA’s Juno spacecraft will come within 222 miles (358 kilometers) of the surface of Jupiter’s ice-covered […]

The Secrets of Jupiter

The Secrets of Jupiter

Discover the top five mysteries that ESA’s Jupiter Icy Moons Explorer (Juice) mission will solve. Jupiter, its magnetic environment, and its moons form one of the most intriguing systems in the Solar System. Juice, planned for launch in 2023 and arrival at Jupiter in 2031, will reveal more about this fascinating planet and its natural […]

Jupiter’s Moon Europa to Obscure Distant Star

Jupiter’s moon Europa to obscure distant star

On 19 June 2022, Jupiter’s intriguing moon Europa will pass in front of a distant star, making that star appear to disappear for at least a minute. This event will be easy to see with any size of telescope from certain parts of Africa. By timing the event and then comparing the observations from different […]

Greenland Ice, Jupiter Moon Share Similar Feature

Greenland Ice, Jupiter Moon Share Similar Feature

The surface geology of Jupiter’s icy moon Europa is on display in this view made from images taken by NASA’s Galileo spacecraft in the late 1990s.  Credit: NASA/JPL-Caltech/SETI Institute Parallel ice ridges, a common feature on Jupiter’s moon Europa, are found on Greenland’s ice sheet – and could bode well for Europa’s potential habitability. Parallel […]

Juice’s journey to Jupiter begins in April 2023

Juice's journey to Jupiter begins in April 2023

ESA’s Jupiter Icy Moons Explorer, Juice, is set to embark on an eight-year cruise to Jupiter starting April 2023. The mission will investigate the emergence of habitable worlds around gas giants and the Jupiter system as an archetype for the numerous giant planets now known to orbit other stars. This animation depicts Juice’s journey to […]

NASA Telescope Spots Highest-Energy Light Ever Detected From Jupiter

NASA Telescope Spots Highest-Energy Light Ever Detected From Jupiter

Jupiter’s southern hemisphere is shown in this image from NASA’s Juno mission. New observations by NASA’s NuSTAR reveal that auroras near both the planet’s poles emit high-energy X-rays, which are produced when accelerated particles collide with Jupiter’s atmosphere.  Credit: Enhanced image by Kevin M.
