The relatively well-preserved ancient crust of Mars provides a natural window into early planetary evolution not available on Earth. Mars has generally...
The end-Cretaceous mass extinction, which included the elimination of all non-avian dinosaurs, occurred after the impact of the Chicxulub asteroid and...
Revealed by 3D seismic imaging, the newly-discovered water reservoir lies 3.2 km (2 miles) under the ocean floor off the coast of New Zealand, where it...
New research shows that long-lived volcanism, driven by early, energetic collisions on Venus, offers an explanation of its young surface age with stagnant-lid...
The 50-km-diameter granitic system discovered below the far side feature known as Compton-Belkovich Volcanic Complex likely was formed from the cooling...
On January 15, 2022, Hunga Volcano in Tonga produced the most violent eruption in the modern satellite era, sending a water-rich plume at least 58 km (36...
Precursors of the molecules needed for the origin of life may have been generated by chemical reactions promoted by meteoritic and volcanic particles approximately...
The newly-discovered planet has a radius of 1.03 Earth radii and a temperature between 27 and 127 degrees Celsius (81-261 degrees Fahrenheit), with the...
There are many thousands of volcanoes on the surface of Venus. These volcanoes provide clues into the interior properties of the planet, properties that...
A so-called light-toned deposit (LTD) in Eastern Noctis Labyrinthus, about 160 km (99.4 miles) north-west of Oudemans crater near Mars’ equator, presents...
Planetary scientists have examined volcanic areas on Venus that were imaged two or three times by NASA’s Magellan spacecraft and identified a 2.2-km2...
Earth has a hot core that heats the surrounding mantle, which carries that heat up to the planet’s lithosphere. The heat is then lost to space, cooling...
Tridymite is a high-temperature, low-pressure form of quartz that is extremely rare on Earth, and it wasn’t clear how a chunk of it ended up in Gale...
An ancient impact that formed the South Pole-Aitken basin, a vast impact structure on the far side of the Moon, would have created a massive plume of heat...
Using seismic data from NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander, planetary researchers...
One or more volcanic eruptions preceded the majority (62 of 68) of dynastic collapses in China over the past 2,000 years, according to new research led...
The Carnian stage (lasted from 237 to 227 million years ago) of the Triassic period marks one of the most significant intervals of the past 250 million...
Using high-resolution images from NASA’s Mars Reconnaissance Orbiter, planetary scientists have discovered 4-billion-year-old layered deposits containing...
In 2020, planetary scientists detected small amounts of the biosignature gas phosphine (PH3) in the atmosphere of Venus using the James Clerk Maxwell Telescope...
