Mars today is a cold, dry world, but it may not always have been so. Recent studies increasingly indicate that the planet once had a thicker, denser atmosphere...
Recent radar observations from ESA’s Mars Express spacecraft were interpreted as evidence for melting beneath the south polar ice cap of Mars. Now, a...
Acquisition of freshwater is problematic for sea snakes living in oceanic environments that are distant from sources of freshwater associated with land....
By analyzing several years of weather radar observations in Finland, a research team led by University of Helsinki scientists has discovered that planes...
Ancient inhabitants of Easter Island (Rapa Nui) built their famous statues (moai) and megalithic platforms (ahu) that supported them near the island’s...
New images from the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express spacecraft show an impact crater in the northern lowlands of Mars. Known...
The surface of the dwarf planet Ceres may contain several times the concentration of carbon than is present in the most carbon-rich, primitive meteorites...
Astronomers using the Near-Infrared Spectrograph (NIRSPEC) on the Keck II telescope at the W. M. Keck Observatory have confirmed the existence of water...
From studying rock formations from satellite images, planetary researchers know that hundreds of craters across the Martian surface were once filled with...
A study led by Pennsylvania State University’s Dr. Asher Rosinger suggests that those who don’t feel well after a night of poor sleep may want to consider...
Bacteria thrive in showerheads and throughout household water distribution systems. While most of these bacteria are innocuous, some are potential pathogens,...
The impact that formed Mercury’s spectacular 100-km (62-mile) wide Hokusai crater, named after the famous Japanese artist, who created the Great Wave...
Caltech researcher Vlada Stamenković and co-authors calculated that if liquid water exists on the Red Planet, it could contain more oxygen than previously...
Ancient inhabitants of Easter Island (Rapa Nui) survived periods of drought due to their utilization of brackish groundwater discharge that surfaces buoyantly...
By looking from two ground-based telescopes at wavelengths sensitive to thermal radiation leaking from the depths of Jupiter’s mysterious, roiling storm...
Astronomers have largely assumed that water-world exoplanets would not support the cycling of minerals and gases that keeps the climate stable on Earth,...
A team of researchers led by Dr. Shuai Li of the University of Hawaii and Brown University has directly observed definitive evidence of surface-exposed...
A research team led by Harvard University astronomer Li Zeng has shown that water is likely to be a major component of extrasolar planets which are between...
