An energetic head-on collision between a large planetary embryo and the proto-Jupiter about 4.5 billion years ago could explain puzzling gravitational...
A new study, published in the journal Scientific Reports, has ruled out the possibility that the levels of methane detected in the Martian atmosphere could...
The NASA/ESA Hubble Space Telescope obtained a detailed image of Jupiter on June 27, 2019, when the gas giant was approximately 400 million miles (644...
New research by scientists from Harvard University, NASA’s Jet Propulsion Laboratory and the UK Centre for Astrobiology shows that widespread regions...
Earth’s magnetic field protects and makes our planet habitable by stopping harmful high-energy particles from space, including from the Sun. The source...
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...
