An asteroid struck Mars 11 million years ago and sent pieces of the planet hurtling through space; one of these chunks eventually crashed into the Earth....
Sedimentary mineral deposits found on the surface of Mars may have been left by an ancient sea 3.5 billion years ago. New results from China’s Tianwen-1/Zhurong...
On Earth, solar radiation can transmit down to multiple meters within ice, depending on its optical properties. Organisms within ice can harness energy...
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which...
Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian...
Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for...
The images in the Martian Cloud Atlas have been captured by the High Resolution Stereo Camera (HRSC) instrument on ESA’s Mars Express spacecraft.

Mars’ water history is fundamental to understanding an evolution of Earth-like planets. Water escapes to space as atoms, and hydrogen (H) atoms escape...
Chloride deposits are markers for early Mars’ aqueous past, with important implications for the understanding of the Martian climate and habitability....
New data about the Martian crust gathered by NASA’s InSight lander allowed geophysicists at the University of California San Diego and the University...
One-third of Mars’ surface has shallow-buried water, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require...
This new image from the High Resolution Stereo Camera (HRSC) onboard ESA’s Mars Express spacecraft shows Caralis Chaos, broken-down and dried-up remnants...
Yellow crystals of elemental sulfur were revealed after NASA’s Curiosity rover happened to drive over a rock and crack it open on May 30, 2024, according...
In a new study, planetary scientists found strong similarities between soils found in Gale Crater on Mars and those of Canada’s Newfoundland, a cold...
Current impact rates at Mars could be 2-10 times higher than previously estimated, depending on the size of the meteoroids, according to new research.
Mars;...
Using high-resolution color images from ESA’s Trace Gas Orbiter (TGO) and Mars Express missions, planetary researchers have found evidence for morning...
In May 2017, NASA’s Curiosity rover observed higher than usual amounts of manganese in the lakebed rocks within Gale crater, Mars. These sedimentary...
