ESA’s Mars Express orbiter has observed several local and regional dust storms brewing at the north pole of the Red Planet.
A dust storm underway at...
The Sample Analysis at Mars (SAM) tunable laser spectrometer onboard Curiosity last week detected surprisingly high levels of the gas methane at Gale Crater:...
Planetary scientists have long observed water-ice clouds in the Martian middle atmosphere (18.6-37.2 miles, or 30-60 km, above the surface). Now, a University...
Although NASA’s Cassini mission ended in 2017, science continues to flow from the data collected. In a series of papers in the journal Science, planetary...
The modern mineral classification system, developed by the American geologist and mineralogist James Dwight Dana in the 1850s, categorizes more than 5,400...
Planetary researchers using data from the Shallow Radar (SHARAD) instrument on NASA’s Mars Reconnaissance Orbiter have discovered rich deposits of water...
According to new research, published in the journal Geology, processes not involved in controlling sand movement on Earth play major roles on the Red Planet,...
Planetary researchers from NASA’s Juno mission made the first detection beyond Earth of an internal magnetic field that changes over time — a phenomenon...
In April 2019, NASA’s InSight lander used its Instrument Deployment Camera (IDC) to capture a series of Martian sunrise and sunset images.
NASA’s InSight...
The SEIS (Seismic Experiment for Interior Structure) instrument on NASA’s InSight lander detected the faint seismic signal on April 6, 2019, the lander’s...
The discovery of life on Mars would get pretty much everyone excited. But the scientists hunting for it would probably be happy no matter what the outcome...
Mars is dry today, but numerous ancient rivers are found across the planet’s surface and their existence is a challenge to models of planetary climate...
A new theory on the thermal evolution of Earth explains why the planet’s upper mantle was cool enough to produce diamonds in the Archean Eon between...
A series of images taken by the NASA/ESA Hubble Space Telescope documents the formation of a Great Dark Spot on Neptune for the first time.
This is a composite...
After eight months of effort and sending more than a thousand commands in an attempt to restore contact with the Mars rover Opportunity, NASA declared...
A team of astronomers from the U.S. Naval Research Laboratory in Washington, DC, and the University of Colorado, Boulder, has found evidence for a fine...
Future manned trips to Mars will require on-site resources, including water, and planetary scientists from a project called ‘Subsurface Water Ice Mapping...
For several years, scientists have tried to explain why so many pairs of exoplanets have an odd configuration — their orbits seem to have been pushed...
