Mars is cold today but once had water lakes and flowing rivers. The early warm climate cannot be explained by basic models of the early Mars greenhouse...
1I/‘Oumuamua, a strange object of extrasolar origin discovered on October 19, 2017 by the Pan-STARRS 1 telescope, was small, about half as long as a...
The deep ice at Camp Century in northwestern Greenland entirely melted at least once within the last million years and was covered with vegetation, including...
Ice XIX is the second hydrogen-partially-ordered phase of ice VI, a previously known form of ice that exists at pressures around 1 GPa and temperatures...
The usual liquid state of water that we are all familiar with corresponds to liquid water at normal temperatures. However, a new study published in the...
A possible subterranean river flows from the deep interior of Greenland to Petermann Fjord, suggests a paper published in The Cryosphere.
A possible subglacial...
Glycine and other amino acids form in dense interstellar clouds well before they transform into new stars and planets, suggests a new study led by researchers...
A team of scientists from Lamont-Doherty Earth Observatory at Columbia University has discovered paleolake basin situated beneath the ice sheet in northwest...
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...
Using the spectral data collected by the Visual and Infrared Mapping Spectrometer (VIMS) onboard NASA’s Cassini spacecraft, a team of researchers has...
The bright frosts observed in 2015 in the equatorial region of Cthulhu on Pluto are mostly made of methane-rich ice, according to new research.
This image,...
Spectral data gathered by the Visual and Infrared Mapping Spectrometer (VIMS) onboard NASA’s Cassini spacecraft provide strong evidence that the northern...
The Little Ice Age, a period of global cooling that lasted from the early 14th century to the mid-19th century, was triggered by an exceptionally large...
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...
