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...
Astronomers using the NASA/ESA Hubble Space Telescope observed Jupiter’s most distinctive feature, the Great Red Spot, with on eight dates over a single,...
In a new study, astronomers compared high-resolution images of Uranus from the NASA/ESA Hubble Space Telescope to the more-distant view from NASA’s New...
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which...
In August 2024, ESA’s JUpiter ICy Moons Explorer (JUICE) made history with a daring Moon-Earth flyby and double gravity assist maneuver. As the spacecraft...
The Moon may have been captured during a close encounter between a young Earth and a terrestrial binary (a system of the Moon and another rocky object),...
Using data from the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected carbon dioxide...
During the Mesozoic era, between 250 and 120 million years ago, an ancient seafloor sank deep into Earth in the East Pacific Rise, a tectonic plate boundary...
Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide. But 3.5 billion years ago, the Martian...
Breakup of an asteroid passing within Earth’s Roche limit likely formed the debris ring during the middle Ordovician period, according to new research...
Primordial black holes are one of the strongest candidates for the Universe’s dark matter. In this scenario, their abundance would be large enough for...
Using images from the JunoCam instrument aboard NASA’s Juno spacecraft, planetary scientists have spotted a fresh volcano with multiple lava flows and...
