NASA's Curiosity Mars rover viewed these yellow crystals of elemental sulfur using its Mast Camera. The discovery marks the first time this mineral has ever been found in a pure form on Mars.
According to a new analysis of the Lafayette Meteorite, minerals within it formed in the presence of water 742 million years ago. It's a real breakthrough in the dating of aqueous minerals on Mars.
Astrobiologist Dirk Schulze-Makuch believes that humans may have unintentionally killed life on Mars in the 1970s.
A Chinese rover has brought forth evidence that hints at the likelihood of a massive ocean, covering almost a third of the Red Planet, that existed billions of years ago.
The science team thinks that igneous and/or metamorphic processes likely formed the rock.
The hidden Mars structures are mysterious because they appear to be significantly denser than their surroundings.
New data about the Martian crust gathered by NASA's InSight lander allowed geophysicists to estimate that the amount of groundwater could cover the entire planet to a depth of between 1 and 2 km.
Nasa has announced the first detection of possible biosignatures in a rock on the surface of Mars.
Among several recent findings, the rover has found rocks made of pure sulfur — a first on the Red Planet.
Mosses are among Earth's great terraformers, turning barren rock into fertile soils, and now a team of scientists is proposing these non-vascular plants could do the same on Mars.
A team of researchers has uncovered evidence of its origins in the atmosphere, where carbon dioxide bathed in ultraviolet sunlight reacted to form a mist of carbon molecules that rained onto the planet's surface.
An international team of researchers combine orbital imagery with seismological data from NASA’s Mars InSight lander to derive a new impact rate for meteorite strikes on Mars.
After months of driving, Perseverance has finally arrived at "Bright Angel", discovering oddly textured rock unlike any the rover has seen before.
In addition to producing auroras, a recent extreme storm provided more detail on how much radiation future astronauts could encounter on the Red Planet.
Morning images show frost briefly coating at least four colossal volcanoes: Olympus Mons, Arsia Mons, Ascraeus Mons, and Ceraunius Tholus.
