Surface landforms called double ridges occur across every sector of Jupiter’s icy moon Europa and can be hundreds of kilometers in length. In new research,...
Jupiter’s moon Io is the most volcanically active body in the Solar System, and the body that is known to be most rapidly resurfaced. Surface modification...
The atmosphere of Jupiter is enriched with heavy elements by a factor of about 3 compared to a protosolar composition. The origin of this enrichment and...
Some icy moons in the outer Solar System likely contain an ocean beneath their ice shells. Jupiter’s moon Europa is thought to have an ocean beneath...
NASA’s Juno spacecraft has snapped a lovely photo of its target planet, Jupiter, and two Jovian moons: Io and Europa.
This Juno image shows Jupiter,...
A new image from the JunoCam instrument aboard NASA’s Juno spacecraft shows a large crater on Ganymede, the Jupiter’s largest moon.
This image of Ganymede...
The magnetosphere of Ganymede, the Jupiter’s largest moon, is a source of electric and magnetic radio emissions, which have been monitored by the Waves...
Juno launched on August 5, 2011 and successfully entered Jupiter’s orbit on July 4, 2016. During each of the spacecraft’s 37 passes of Jupiter to date,...
NASA’s Lucy spacecraft was launched on October 16, 2021, at 5:34 a.m. EDT aboard a United Launch Alliance (ULA) Atlas V rocket out of Space Launch Complex...
Using a technique called gravitational microlensing, which occurs when a star close to Earth momentarily aligns with a more distant star, astronomers have...
Observations by the NASA/ESA Hubble Space Telescope in far-ultraviolet light of Jupiter’s icy moons were used in the past to detect molecular oxygen...
Using data from the WFC3/UVIS instrument on board the NASA/ESA Hubble Space Telescope, a team of astronomers has measured the horizontal winds in Jupiter’s...
Using data from the Jovian Infrared Auroral Mapper (JIRAM) instrument onboard NASA’s Juno spacecraft, researchers have produced a new infrared map of...
The upper atmosphere of Jupiter is hotter than expected from the amount of sunlight that it receives: the average temperature should be about minus 73...
Jupiter’s icy satellite Ganymede is the largest moon in the Solar System. Water ice on its surface is frozen solid in frigid temperatures as low as minus...
Planetary scientists are studying the cumulative effects of small impacts on the surface of Jupiter’s moon Europa as they prepare to explore the icy...
The rapidly rotating, strong magnetic field of Jupiter provides a natural lab that is key to understanding the dynamics of high-energy plasmas. Spectacular...
The recent suggestion of phosphine gas in the atmosphere of Venus has regenerated interest in the idea of life in clouds; however, such analyses usually...
