A so-called light-toned deposit (LTD) in Eastern Noctis Labyrinthus, about 160 km (99.4 miles) north-west of Oudemans crater near Mars’ equator, presents...
Rocky exoplanets orbiting red dwarf (M-dwarf) stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets...
Monell Chemical Senses Center researcher Yali Zhang and colleagues identified a previously unknown chloride ion channel, which they named alkaliphile (Alka),...
Among animals, humans stand out in their consummate propensity to self-induce altered states of mind. Archaeology, history and ethnography show these activities...
In new research, planetary scientists from the University of Maryland and elsewhere analyzed melted meteorites that had been floating around in space since...
The new animation shows the gamma-ray sky’s frenzied activity during a year of observations by the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray...
Planetary scientists have examined volcanic areas on Venus that were imaged two or three times by NASA’s Magellan spacecraft and identified a 2.2-km2...
Wolf-Rayet stars are in the process of casting off their outer layers, resulting in their characteristic halos of gas and dust. The new Webb images of...
Xanthine, which is found in coffee, tea and chocolate, may play a role in the generation of interleukin-17-producing T helper (Th17) cells, an important...
