These bright (hot) ‘thermal rings’ are a common phenomenon, and they are indicative of active lava lakes, according to a new analysis of data from the Jovian Infrared Auroral Mapper…
Using radar data from NASA’s Magellan mission, planetary scientists have detected volcanic-related flow features in two different regions of Venus: on the western flank of Sif Mons and in western…
Sulfur and chlorine isotopes in Io’s atmosphere indicate that it has been volcanically active for the entire 4.57 billion-year history of the Solar System. This global view of Io was…
In December 2023 and February 2024, NASA’s Juno spacecraft made extremely close flybys of Jupiter’s volcanic moon Io, getting within about 1,500 km (930 miles) of the surface and obtaining…
Provisionally designated Noctis Mons, the newly-discovered volcano is located just south of Mars’ equator, in Eastern Noctis Labyrinthus, west of Valles Marineris, the planet’s vast canyon system. Noctis Mons. Image…
The relatively well-preserved ancient crust of Mars provides a natural window into early planetary evolution not available on Earth. Mars has generally been considered a one-plate basaltic planet, though recent…
On February 3, 2024, NASA’s Juno spacecraft made a second close flyby of Io, the fifth of Jupiter’s moons and the third largest. Like the previous flyby on December 30,…
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 tectonics. This volcanic activity is fuelled by…
The 50-km-diameter granitic system discovered below the far side feature known as Compton-Belkovich Volcanic Complex likely was formed from the cooling of molten lava that fed a volcano or volcanoes…
Precursors of the molecules needed for the origin of life may have been generated by chemical reactions promoted by meteoritic and volcanic particles approximately 4.4 billion years ago, says a…
