The first-ever measurements of liquid water at temperatures between 135 K (minus 138.15 degrees Celsius, or minus 216.7 degrees Fahrenheit) and 235 K (minus...
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...
The southern highlands of Mars are dissected by hundreds of ancient valley networks (3.9-3.5 billion years old), which are evidence that water once sculpted...
Using data from the Sample Analysis at Mars (SAM) instrument on NASA’s rover Curiosity, researchers have found that certain minerals in rocks at Gale...
In 2011, NASA’s MESSENGER orbiter detected signals typical of glacial ice near the poles on Mercury. The ice was dingy and lurked in permanent shadows...
The High Resolution Stereo Camera on ESA’s Mars Express orbiter has captured stunning images of Moreux crater, a huge impact crater in the Terra Sabaea...
An international team of researchers has found bacterial communities within microscopic spheroidal aggregates of dolomite, oil and water found in sheets...
A team of U.S. researchers has found ancient viruses and bacteria in ice from two cores drilled on the summit and plateau of the Guliya ice cap in northwestern...
Using data from NASA’s Mars Reconnaissance Orbiter and Mars Odyssey orbiter, a team of planetary researchers have crated a map of the water ice depth...
The two Martian hemispheres are drastically different; the smooth northern lowlands sit up to 3 km below the rugged southern highlands, and the surface...
An international team of scientists from the UK and Japan has found ‘fossilized asteroidal ice’ and pristine dust materials in a 4.6-billion-year-old...
The smallest droplet of water in which ice can form is only as big as 90 water molecules, according to new research.
Moberg et al show that the smallest...
Astronomers have detected the signature of vaporized water in the coma of the interstellar comet 2I/Borisov, also known as C/2019 Q4.
On October 12, 2019,...
Unusually large and long ridges documented in massive landslides across our Solar System are commonly associated with the presence of ancient ice layers....
Lunar orbiters such as India’s Chandrayaan-1 spacecraft and NASA’s Lunar Reconnaissance Orbiter (LRO) recently detected water icy on the floor of some...
Saturn’s moon Enceladus is erupting a plume of gas and ice grains from its south pole. According to new research using data from NASA’s Cassini mission,...
Lunar orbiters recently detected water frost on the floor of some of the south polar craters, regions that are known to be very cold and can trap water....
Planetary scientists have long observed water-ice clouds in the Martian middle atmosphere (18.6-37.2 miles, or 30-60 km, above the surface). Now, a University...
NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) observed the hyperactive Jupiter-family comet 46P/Wirtanen as it made its closest approach...
Many icy bodies in our Solar System have underground oceans. On the dwarf planet Pluto, an area called Sputnik Planitia suggests the presence of a subsurface...
