Planetary scientists have discovered more than 15,000 km of ancient riverbeds in Noachis Terra, a region in Mars’ southern highlands. This discovery...
Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above...
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...
The subsurface of Mars during the Noachian period was likely to have been habitable for microorganisms that feed on hydrogen and produce methane, according...
A 54-km- (33.5-mile) diameter Noachian-aged crater with neither inlet nor outlet channels is distinct from previously documented crater basin lakes on...
Using data from the Context Camera aboard NASA’s Mars Reconnaissance Orbiter, planetary researchers have generated an 8-trillion-pixel global map of...
According to a new study published in the journal Science Advances, the Martian subsurface would have been the most habitable region for simple life forms...
ESA’s Mars Express orbiter has spotted three overlapping craters in Noachis Terra, an extensive landmass in the southern hemisphere of Mars.
This image...
While the present-day Martian surface is generally dry and cold, its sedimentary rocks contain compelling evidence for the former presence of liquid water....
Four-billion-year-old carbonates in a Martian meteorite called Allan Hills (ALH) 84001 contain nitrogen-bearing organic molecules, according to a new study...
Mars had right conditions for subsurface life some 3.7 to 4.1 billion years ago (Noachian period), according to new research from Brown University.
An...
On Mars, phyllosilicate (clay) minerals are widespread in terrains that date back to the Noachian period, 4.1 to 3.7 billion years ago. Phyllosilicates...
