Findings show substantial amounts of H₂O could only have been delivered to Earth by means of unmelted material, such as chondrites, and not melted material such as achondrites. The results could have important implications for the search for water—and life—on other planets

Searching for evidence of life on Mars is a major impetus for exploration, however, current Mars mission instruments lack the essential sensitivity to identify life traces in Chilean desert samples that strongly resemble the martian area currently under study by NASA’s Perseverance rover.

Not long ago it was thought Earth’s structure was comprised of four distinct layers: the crust, the mantle, the outer core and the inner core. By analysing the variation of travel times of seismic waves for different earthquakes scientists believe there may be a fifth layer.

Researchers discover a network of fractures in Gale Crater filled with Opal, a water-rich mineraloid. This water-rich subsurface network would have been shielded from modern harsh surface conditions, allowing for a potentially habitable environment on Mars in a more recent era.

Magma on Mars Likely - Until now, Mars has been generally considered a geologically dead planet. An international team of researchers led by ETH Zurich now reports that seismic signals indicate volcanism still plays an active role in shaping the Martian surface.
