As our Solar System orbits the Milky Way, it encounters various environments, including dense regions of the interstellar medium. These encounters can...
Using data gathered by China’s Zhurong rover, planetary researchers have identified hidden layers of rock under the Martian surface that strongly suggest...
New images, taken over 16 min on January 17, 2025 by the Mastcam instrument on NASA’s Curiosity rover, show noctilucent, or twilight clouds, in the atmosphere...
Geoscientists from the University of Southern California, Los Angeles, the Institute of Geology and Geophysics at the Chinese Academy of Sciences, Cornell...
A new analysis of magmatic iron meteorites challenges traditional theories about why Earth and Mars are depleted in moderately volatile elements.
The Bendego...
In a new study, planetary researchers used global and high-resolution orbital imaging to discover a fresh, 21.5-m (71-foot) impact crater that appeared...
A team of planetary researchers led by Caltech has determined the chemical mechanisms by which the ancient Mars was able to sustain enough warmth in its...
In a study published in the journal Nature Geoscience, planetary researchers used high-resolution images and compositional data captured by orbiters to...
Astronomers have long thought that the upper clouds of Jupiter, which create the planet’s iconic pale brown belts, are made of frozen ammonia. But a...
In a new paper, planetary researchers from Texas A&M University and the University of Washington introduce a new thermodynamic concept called the centotectic...
Planetary scientists using the High Resolution Stereo Camera on ESA’s Mars Express spacecraft have captured stunning images of an enigmatic landscape...
Mars is located at the extreme limits of brine stability; and only a combination of the most favorable environmental conditions and lowest eutectic temperature...
Saturn’s icy rings could be much older than they appear due to their resistance to pollution from impacts with rocky debris.
Hyodo et al. suggest that...
In 2003, Hubble provided evidence of a massive exoplanet around a very old star. Such stars possess only small amounts of heavier elements that are the...
The OPAL (Outer Planet Atmospheres Legacy) program obtains long-term baseline observations of Jupiter, Saturn, Uranus, and Neptune in order to understand...
Planetary researcher Tereza Constantinou and her colleagues at the University of Cambridge have examined the chemical composition of the Venusian atmosphere...
Primordial black holes have been theorized for decades and could even be ever-elusive dark matter. Still, no primordial black hole has ever been observed....
These Earth-size ovals at Jupiter’s north and south poles are visible only at ultraviolet (UV) wavelengths, and appear and disappear seemingly at random,...
Scientists from Curtin University and the University of Adelaide have analyzed a 4.45-billion-year-old zircon grain from a famous Martian meteorite called...
