Europa, the sixth of Jupiter’s moons and the fourth largest, has a subsurface ocean covered by an icy shell. Despite evidence for plumes on the icy moon,...
Jupiter’s icy moon Europa is bombarded by a constant and intense blast of radiation from the gas giant. Different salty compounds on the moon’s surface...
NASA’s Juno spacecraft has been in orbit around Jupiter since 2016. One of its instruments is the ultraviolet spectrograph (UVS), which is primarily...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted airborne plumes of sulfur dioxide (SO2), sulfur monoxide (SO), and...
Early in the formation of Jupiter as a planet, it moved closer to and then away from the Sun due to interactions with the planetary disk of the young Solar...
Two new photos, taken with the NASA/ESA Hubble Space Telescope, show Jupiter with its turbulent atmosphere and giant storms. One of the images also features...
A new study suggests that during Jupiter’s violent storms, hailstones form from a cooled mixture of water and ammonia gas, similar to the process in...
Other stars could have as many as seven Earth-like planets in the absence of farther out giant planets, according to a new study led by the University...
The Jovian Infrared Auroral Mapper (JIRAM) instrument onboard NASA’s Juno spacecraft has captured the first infrared images of the north pole of Ganymede,...
A duo of U.S. planetary scientists has calculated that water in the subsurface ocean of Jupiter’s icy moon Europa could have been formed by breakdown...
NASA’s Juno orbiter captured a beautiful image during its 25th close flyby of Jupiter in February 2020.
This image of Jupiter was taken on February 17,...
Multiwavelength observations from the NASA/ESA Hubble Space Telescope and Gemini Observatory combined with close-up views from NASA’s Juno spacecraft...
The newly-remastered images show the icy surface of Europa, the sixth of Jupiter’s moons and the fourth largest, in enhanced color.
This map shows locations...
Brown dwarfs are cool, dim objects that have a size between that of a gas giant, such as Jupiter or Saturn, and that of a Sun-like star. Sometimes called...
Water makes up about 0.25% (almost three times that of the Sun) of the molecules in Jupiter’s atmospheric molecules at the gas giant’s equator, according...
