Using data from the Jovian Infrared Auroral Mapper (JIRAM) instrument onboard NASA’s Juno spacecraft, researchers have produced a new infrared map of...
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...
A team of planetary scientists from the Department of Space Studies at the Southwest Research Institute has combined computer models of asteroid evolution...
An international team of astrophysicists has announced a new scientific project to search for evidence of potential astro-archeological artifacts or active...
According to new analyses of data from the Seismic Experiment for Interior Structure (SEIS) instrument deployed during NASA’s InSight mission, Mars likely...
Jupiter’s icy satellite Ganymede is the largest moon in the Solar System. Water ice on its surface is frozen solid in frigid temperatures as low as minus...
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...
The long-period comet C/2019 Y4 (ATLAS) fragmented during its perihelion in April 2020. About two months later, ESA’s Solar Orbiter observed the dusty...
Astronomers with Las Cumbres Observatory have captured a new image of the recently-discovered giant comet C/2014 UN271 (Bernardinelli-Bernstein).
This...
Planetary scientists are studying the cumulative effects of small impacts on the surface of Jupiter’s moon Europa as they prepare to explore the icy...
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...
Using the Near-Infrared Spectrograph (NIRSPEC) instrument at the Keck II telescope, astronomers conducted near-infrared spectroscopic observations of the...
Once the Earth was fully formed about 4.5 billion years ago, its subsequent evolution was governed by complex geophysical processes. The planet, however,...
Saturn’s 500-km- (300-mile) diameter moon Enceladus is covered in ice which contains many long fractures or rifts, including fractures called tiger stripes....
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...
Observations from NASA’s Cassini spacecraft established that Enceladus, the sixth-largest of Saturn’s moons, has a global subsurface ocean. An analysis...
