Lava planets are rocky exoplanets that orbit so close to their host star that their dayside is hot enough to melt silicate rock.

The Martian meteorite Northwest Africa (NWA) 16254 is a 406-g gabbroic shergottite found two years ago in Algeria.
Image of the entire NWA 16254 sample...
Magma reservoirs beneath volcanoes along the Cascade Range arc vary in depth, size and complexity, but upper-crustal magma bodies are widespread, according...
There is extensive geologic evidence of ancient volcanic activity on the Moon, but it is unclear how long that volcanism persisted. Magma fountains produce...
In the new study, Dr. David Hernández Uribe from the University of Illinois Chicago used computer models to study the formation of magmas thought to hold...
Gas bubbling up from a lava-covered surface on the super-Earth exoplanet 55 Cancri e may feed an atmosphere rich in carbon dioxide or carbon monoxide,...
New research from the University of Bristol sheds light on the origin of titanium-rich basaltic magmas on the Moon.
A map of the titanium abundances of...
Mars’ liquid iron alloy core is surrounded by a layer of fully molten silicate (magma) about 150 km thick, according to a pair of papers published in...
By analyzing tiny lunar zircon crystals gathered by Apollo 17 astronauts in 1972, planetary scientists recalculated the age of the Moon. Although previous...
Lava worlds are a potential emerging population of hot super-Earth exoplanets that are on close-in orbits around their host stars, with likely partially...
Previous research estimated that it took hundreds of million years for early Earth’s magma ocean to solidify, but new research narrows these large uncertainties...
Each year, about 2 kg of helium-3, a rare isotope of helium gas, escapes from Earth’s interior, mostly along the mid-ocean ridge system. Helium-3 is...
Ultra-low velocity zones sit beneath the central Pacific and Africa, atop the outer core of Earth. In these areas, seismic waves slow by as much as half,...
Impact bombardment has played a significant role in the evolution of the Earth-Moon system. However, it is suggested from different perspectives, including...
Jupiter’s moon Europa harbors underneath a tectonically modified ice shell a salty ocean in direct contact with its rocky interior. Such an oceanic environment...
Using the NASA/ESA Hubble Space Telescope, astronomers have found evidence of volcanic activity reforming the atmosphere of Gliese 1132b, a rocky exoplanet...
