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...
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...
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have captured high-resolution images of eight protoplanetary disks in Sigma...
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...
On Earth, solar radiation can transmit down to multiple meters within ice, depending on its optical properties. Organisms within ice can harness energy...
