Using data from the Jovian InfraRed Auroral Mapper (JIRAM) aboard NASA’s Juno spacecraft, planetary scientists have detected hydrated sodium chloride,...
Two new papers in the Astronomical Journal show that in some multiplanet systems, giant planets tend to kick their smaller neighbors out of orbit and wreak...
The newly-discovered intense (140 m/s) jet is confined to ±3° of Jupiter’s equator, is approximately 4,800 km wide, and is located in the gas giant’s...
Young moving stellar groups are the best targets for direct imaging of exoplanets and four massive Jupiter-like planets have been already discovered in...
Jupiter’s icy moon Europa has an ocean beneath a crust of water ice. Solid carbon dioxide has previously been observed on the surface, but the source...
Jupiter’s moon Ganymede is the only satellite in the Solar System known to have an intrinsic magnetic field. Interactions between this field and the...
Many planetary scientists studying Jupiter’s moon Europa assumed that it formed with a metallic core during or shortly after accretion. New research...
The radar properties of icy satellites of Jupiter and Saturn commonly differ by more than an order of magnitude from those of rocky planets because of...
The subsurface ocean of Jupiter’s icy moon Europa is heated from below via tidal heating and radioactive decay of the rocky interior, while being cooled...
Astronomers using NASA’s Infrared Telescope Facility (IRTF) telescope at Mauna Kea Observatory have captured and analyzed visible and near-infrared reflectance...
University of Washington researcher Baptiste Journaux and colleagues believe the newly-created substances could form at the surface and bottom of deep...
Using data from NSF’s Karl G. Jansky Very Large Array (VLA), the Atacama Large Millimeter/submillimeter Array (ALMA) and NASA’s Juno spacecraft, two...
New videos captured by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express orbiter show the rare moment of the Martian moon Deimos passing...
In the search for life beyond Earth, subsurface bodies of water in the outer Solar System are some of the most important targets. That’s why NASA and...
These images of Jupiter’s icy moon Europa were taken by the JunoCam instrument aboard NASA’s Juno spacecraft during a close approach on September 29,...
This black-and-white image of Jupiter’s icy moon Europa was taken by the Stellar Reference Unit (SRU) instrument on board NASA’s Juno orbiter during...
