Planetary science

According to Stanford University Mars experts, NASA’s latest Martian rover will drive a wave of exciting discoveries when it lands on the Red Planet – and possibly alter scientists’ understanding of the blue one it launches from.

The Chicxulub impact crater that is linked to the extinction of the dinosaurs hosted a hydrothermal system that chemically and mineralogically modified more than 100,000 cubic kilometers of Earth’s crust, according to new research.

Learning how liquid silicates behave at extreme temperatures and pressures has been a longstanding challenge in the geosciences.

The former director of NASA Ames discusses how the advent of new activities and players in the exploration and use of space is raising fresh challenges and concerns about planetary protection.

New research indicates river delta deposits within Mars’ Jezero crater – the destination of NASA’s Perseverance rover on the Red Planet – formed over time scales that promoted habitability and enhanced preservation of evidence.

Scientists exploring space are bringing back insights about Earth’s deep past, its complicated relationship with life and our planet’s future.

How did those planets form? Could they exist in our universe? Could Star Wars really happen? Stanford Earth experts on planetary formation, processes and habitability discuss the science behind the fictional saga.

A new study suggests a reason why exoplanets rarely grow larger than Neptune: the planet’s magma oceans begin to eat the sky.

New research using data from NASA’s Spitzer Space Telescope has provided a rare glimpse at the surface of a rocky planet outside our solar system. The planet may be similar to Mercury or Earth’s moon, with little to no atmosphere.
