The many large storms and small white clouds seen in the new Hubble images, taken on January 5 and 6, 2024, are evidence for a lot of activity going on...
NASA’s Europa Clipper spacecraft will carry a triangular metal plate with a special message when it launches in October 2024 and heads toward Jupiter’s...
Using data from the Jovian Auroral Distributions Experiment (JADE) instrument onboard NASA’s Juno spacecraft, planetary scientists have calculated the...
Enceladus is a prime target in the search for life in the Solar System, identified by NASA as the second-highest priority site for a flagship mission in...
NASA has released a beautiful ultraviolet image taken by the Hubble Space Telescope of the gas giant Jupiter.
This Hubble image shows Jupiter in ultraviolet...
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...
