Utopia Planitia, a large lava plain in the northern hemisphere of Mars, has a diameter of roughly 3,300 km (2,051 miles) — just under twice the north-south...
Cryovolcanoes (ice volcanoes) are similar to normal volcanoes but instead of being formed from molten rock, they are made by frozen liquids like ammonia...
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...
Physicists have observed the transition from a previously known cubic phase, ice VII, to the newly-discovered intermediate, and tetragonal, phase, ice...
With thousands of discovered exoplanets and new missions that will explore our Solar System, the search for life in the Universe has entered a new era....
ESA’s Trace Gas Orbiter (TGO) has spotted an ice-rich impact crater in Acidalia Planitia, a Martian plain between the Tharsis volcanic province and Arabia...
During solar storms, the Sun expels large amounts of energetic particles that can react with the atmosphere of Earth and produce cosmogenic isotopes such...
In 2018, the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) instrument onboard ESA’s Mars Express orbiter found evidence of liquid...
Mimas, the smallest and innermost of Saturn’s eight main moons, may be warm enough to harbor a global, liquid water ocean beneath a 24-31-km (15-19-mile)...
ESA’s Trace Gas Orbiter has returned a stunning image of a 4-km- (2.5-mile) wide crater located in Vastitas Borealis, the largest lowland region of Mars.
The...
Planetary researchers using the Fine Resolution Epithermal Neutron Detector (FREND) instrument onboard ESA’s Trace Gas Orbiter (TGO) have found evidence...
University of Exeter’s Dr. Adrien Morison and colleagues have shown how vast ice forms have been shaped in Sputnik Planitia, a nitrogen-ice-filled basin...
One or more volcanic eruptions preceded the majority (62 of 68) of dynastic collapses in China over the past 2,000 years, according to new research led...
The surface pressure on the dwarf planet Pluto is decreasing and that its nitrogen atmosphere is condensing, forming ice on the dwarf planet’s surface,...
Using machine learning, a team of physicists at Lawrence Livermore National Laboratory has studied the phase behaviors of superionic water — a phase...
Using high spatial-resolution data gathered by the Gamma Ray and Neutron Detector (GRaND) aboard NASA’s Dawn spacecraft, planetary researchers have detected...
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...
Microbiologists at the Ohio State University have found that the ancient bacteria and their phages (bacteria-infecting viruses) from Tibetan glacier ice...
Saturn’s 500-km- (300-mile) diameter moon Enceladus is covered in ice which contains many long fractures or rifts, including fractures called tiger stripes....
