Annular modes explain much of the internal variability of Earth’s atmosphere but have never been identified as influential on other planets.
Mars has...
New research shows that the magnetic field of our planet was relatively weak (less than half the strength of the long-term average field) for tens of millions...
Individual regional dust events can boost planetary water loss by a factor of five to ten and represent an important driver of atmospheric evolution on...
On August 4, 2021, NASA’s Ingenuity helicopter performed its 11th flight on Mars, snapping multiple photographs during its trip.
This image shows the...
The upper atmosphere of Jupiter is hotter than expected from the amount of sunlight that it receives: the average temperature should be about minus 73...
New research shows that mean annual temperatures in southeast Australia gradually declined from 27 degrees Celsius during the Middle Eocene epoch to...
According to new analyses of data from the Seismic Experiment for Interior Structure (SEIS) instrument deployed during NASA’s InSight mission, Mars likely...
The ‘methane mystery’ on Mars has been ongoing for many years, with contradictory findings from seveal missions, wuch as ESA’s Mars Express and NASA’s...
Venus is well known for its rotating upper atmosphere, which sweeps around the planet once every 4 Earth days. This is in stark contrast to the rotation...
Along with analyzing rocks using X-rays and ultraviolet light, NASA’s Perseverance rover will zoom in for close-ups of rock surfaces that might show...
In 2020, planetary scientists detected small amounts of the biosignature gas phosphine (PH3) in the atmosphere of Venus using the James Clerk Maxwell Telescope...
The rapidly rotating, strong magnetic field of Jupiter provides a natural lab that is key to understanding the dynamics of high-energy plasmas. Spectacular...
Once the Earth was fully formed about 4.5 billion years ago, its subsequent evolution was governed by complex geophysical processes. The planet, however,...
Earth’s sphere tilts on its axis at an angle of 23.5 degrees; this gives us our seasons, with parts of the planet receiving more direct sunlight in summer...
In 2011, planetary researchers using samples of the solar wind collected by NASA’s Genesis spacecraft found that solar system planetary bodies have a...
Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a...
The Tunable Laser Spectrometer (TLS) in the Sample Analysis at Mars (SAM) chemistry lab onboard NASA’s Curiosity rover has detected atmospheric methane...
The recent suggestion of phosphine gas in the atmosphere of Venus has regenerated interest in the idea of life in clouds; however, such analyses usually...
