Pluto is thought to possess a subsurface ocean beneath its thick ice shell. It has generally been assumed that the dwarf planet formed out of cold material...
A team of U.S. astronomers has calculated internal heating rates for 53 terrestrial exoplanets and found that all of them are likely to have volcanic activity...
Highly purified heavy water has a distinctly sweeter taste than same-purity normal (light) water, according to a study conducted by researchers from the...
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...
Mud flows exposed to the low atmospheric pressures found on Mars will behave similar to lava flows in Hawaii or Iceland, also known as pahoehoe flows,...
A new study shows that pockets of brine can form and persist from the equator to high latitudes on the Martian surface for a few percent of the year for...
A team of researchers from the United States and Canada has found evidence for 4.55-billion-year-old sodium-rich alkaline fluids in the Tagish Lake meteorite,...
While the present-day Martian surface is generally dry and cold, its sedimentary rocks contain compelling evidence for the former presence of liquid water....
Astronomers using NASA’s Neil Gehrels Swift Observatory have tracked water loss from 2I/Borisov, the first known interstellar comet to visit our Solar...
A team of Australian scientists and wildlife ecologists has captured koala drinking behavior in the wild for the first time.
Old female koala showing natural...
The 2018 eruption of Kīlauea volcano in Hawaii was likely initiated by prolonged, and at times extreme, rainfall in the months leading up to the event,...
An approach called the wastewater-based epidemiology (WBE), which is already recognized as an effective way to trace illicit drugs and obtain information...
A team of researchers from the University of Plymouth, Rame Peninsula Beach Care and the Lego Lost at Sea Project examined the extent to which classic...
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...
A team of astronomers from the Institute of Astronomy at the University of Cambridge, UK, has found K2-18b, a planet of almost nine Earth masses in orbit...
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...
A thin-film device made from nanometer-scale protein wires harvested from the microbe Geobacter sulfurreducens can generate continuous electric power in...
