Earlier work has demonstrated that an extremophile bacterium species called Deinococcus radiodurans can survive the radiation, cold, and desiccation associated...
New orbital data reveal that the most recently active volcanic systems on Mars weren’t simple one-off blasts into space; instead, long-lived magmatic...
Known non-biological sources, from meteorites to surface chemistry, fall short of accounting for organic compounds detected by NASA’s Curiosity rover,...
Mars almost certainly once held abundant water. Until now, observations have shown that most atmospheric water loss occurs during the Red Planet’s southern...
NASA’s Perseverance rover has discovered several thousand small, light-toned rock fragments, or float rocks, with some exhibiting spectral signatures...
Using data captured by the SuperCam microphone aboard NASA’s Perseverance rover over two Martian years, planetrary scientists have detected 55 triboelectric...
The new ultraviolet (UV) images from the Imaging Ultraviolet Spectrograph (IUVS) camera aboard NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN)...
The new images from the High Resolution Imaging Science Experiment camera onboard NASA’s Mars Reconnaissance Orbiter will allow astronomers to better...
Thanks to the data collected by the Colour and Stereo Surface Imaging System (CaSSIS) onboard ESA’s Trace Gas Orbiter (TGO) spacecraft orbiting Mars,...
On some of the dune fields on Mars, parallel channels, called linear dune gullies, are found. Contrary to their name these gullies are often highly sinuous....
Exploring the possibility of the survival of life under extraterrestrial conditions is an important goal of astrobiology. In a new study, scientists used...
During its closest approach to Mars on October 3, 2025, 3I/ATLAS was 30 million km away from ESA’s ExoMars Trace Gas Orbiter (TGO).
This image of the...
The newly-discovered mineral, named ferric hydroxysulfate, provides clues about the environment and history of the Red Planet, including the possibility...
Minerals are the building blocks of rocks, and the types of minerals and their chemistry provide critical information about rock formation and history....
The polar vortex is a consequence of Martian seasons, which occur because the planet’s axis is tilted at an angle of 25.2 degrees, according to University...
NASA’s Perseverance rover has explored and sampled igneous and sedimentary rocks within Jezero crater to characterize early Martian geological processes...
On July 24, 2025, the 4,608th Martian day, or Sol, of the mission, NASA’s Curiosity rover imaged wind-eroded rocks shaped like a piece of coral in the...
Radiolysis induced by Galactic cosmic rays could provide a viable energy source for microbial metabolism in the subsurface environments of rocky planetary...
Planetary scientists have discovered more than 15,000 km of ancient riverbeds in Noachis Terra, a region in Mars’ southern highlands. This discovery...
