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...
Dark comets are small bodies with no detected coma that have significant accelerations explainable by outgassing of volatiles, analogous to the first interstellar...
The OPAL (Outer Planet Atmospheres Legacy) program obtains long-term baseline observations of Jupiter, Saturn, Uranus, and Neptune in order to understand...
These asteroids are as small as 10 m across, making them the smallest asteroids ever observed in the main asteroid belt.
An artist’s illustration of...
Planetary researcher Tereza Constantinou and her colleagues at the University of Cambridge have examined the chemical composition of the Venusian atmosphere...
Contradicting the results of several recent studies, the new findings reopen the case that Jupiter-family comets like 67P/Churyumov-Gerasimenko could have...
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...
Several of the icy moons in the Jupiter and Saturn systems appear to possess internal liquid water oceans. Our knowledge of the Uranian moons is more limited...
456P/PANSTARRS, an active, main-belt asteroid first spotted in 2021, is recurrently active, and activity is likely driven by the sublimation of volatile...
An asteroid struck Mars 11 million years ago and sent pieces of the planet hurtling through space; one of these chunks eventually crashed into the Earth....
When NASA’s Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists’ first close glimpse of this ice-giant planet. Alongside the discovery...
A team of scientists from the Lunar and Planetary Laboratory at the University of Arizona, TU Delft, and Caltech has developed a new method to compute...
Sedimentary mineral deposits found on the surface of Mars may have been left by an ancient sea 3.5 billion years ago. New results from China’s Tianwen-1/Zhurong...
