Called ferrihydrite, this iron mineral formed during a cold, wet period on early Mars under oxidative conditions, followed by a transition to the current...
Using data gathered by China’s Zhurong rover, planetary researchers have identified hidden layers of rock under the Martian surface that strongly suggest...
New images, taken over 16 min on January 17, 2025 by the Mastcam instrument on NASA’s Curiosity rover, show noctilucent, or twilight clouds, in the atmosphere...
A new analysis of magmatic iron meteorites challenges traditional theories about why Earth and Mars are depleted in moderately volatile elements.
The Bendego...
In a new study, planetary researchers used global and high-resolution orbital imaging to discover a fresh, 21.5-m (71-foot) impact crater that appeared...
A team of planetary researchers led by Caltech has determined the chemical mechanisms by which the ancient Mars was able to sustain enough warmth in its...
In a study published in the journal Nature Geoscience, planetary researchers used high-resolution images and compositional data captured by orbiters to...
Planetary scientists using the High Resolution Stereo Camera on ESA’s Mars Express spacecraft have captured stunning images of an enigmatic landscape...
Mars is located at the extreme limits of brine stability; and only a combination of the most favorable environmental conditions and lowest eutectic temperature...
Scientists from Curtin University and the University of Adelaide have analyzed a 4.45-billion-year-old zircon grain from a famous Martian meteorite called...
