Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above...
NASA’s Curiosity rover has found evidence of a carbon cycle on ancient Mars, bringing scientists closer to an answer on whether the planet was ever capable...
Recent measurements from NASA’s InSight mission show that Mars’ core is less dense than planetary scientists previously believed. This indicates that...
The rotation period of Uranus was estimated to be 17.24 hours in 1986 from radio auroral measurements made by NASA’s Voyager 2 spacecraft. Using the...
A Martian dust devil can be seen consuming a smaller one in a series of images taken by a navigation camera aboard NASA’s Perseverance rover.
Dust devils...
Certain lichen species can withstand Mars-like conditions with an X-ray radiation dose of 50 Gy (Grays) that is expected on the Mars surface over one year...
An unexpected phenomenon called convection could help explain many of the volcanoes and other features of the Venusian landscape.
Artist’s impression...
A 20-year Hubble study of Uranus provide valuable data for understanding the atmospheric dynamics of this distant ice giant, which can serve as a proxy...
The origin of life on Earth required a supply of phosphorus for the synthesis of universal biomolecules. Closed lakes may have accumulated high concentrations...
Emissions from the upper-atmospheric trihydrogen cation (H3+) have been used to study the global-scale interactions of Jupiter, Saturn and Uranus with...
The Sample Analysis at Mars instrument onboard NASA’s Curiosity rover has detected decane, undecane, and dodecane molecules in a sample from Gale crater.
This...
A team of astronomers from Taiwan, Canada, the United States, and France has observed 128 additional moons orbiting the gas giant Saturn, bringing its...
How lightning is started in thunderstorms is poorly known. With a newly-developed 3D mapping and polarization system, physicists at Los Alamos National...
Atmospheric gravity waves play a crucial role in driving latitudinal air currents on the Red Planet, particularly at high altitudes, according to a new...
Heat from our Sun drives atmospheric temperature changes on Earth, which in turn can affect things like rock properties and underground water movement,...
By chemically analyzing crystals in ancient rocks, scientists from Curtin University, the University of Portsmouth and St. Francis Xavier University discovered...
A team of researchers at the Bayerisches Geoinstitut has conducted high-pressure-temperature laboratory experiments to determine the crystal structure...
Called ferrihydrite, this iron mineral formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current...
