An investigation of Vesta, a massive asteroid that orbits the Sun between Mars and Jupiter, has revealed that the planet-like body has a thicker crust than previously thought, which calls into question the internal structures of other planets in the Solar System.
While all of Earth’s oceans may seem like more than enough water for one planet, a new study published in the journal Science has revealed an ocean’s worth of water may be sitting in the mantle.
A new paper published in the journal Nature rewrites the history of the giant asteroid Vesta, which was recently visited by NASA’s Dawn mission. It was during this mission that the spacecraft used its visible and infrared mapping spectrometer instrument to map out the surface of the asteroid, leading to some new theories and ideas of the space rock.
Scientists broke new ground in the study of deep earthquakes, a poorly understood phenomenon that occurs where the oceanic lithosphere, driven by tectonics, plunges under continental plates – examples are off the coasts of the western United States, Russia and Japan.
Scientists have provided a solution to a 135-year-old mystery in cosmochemistry, saying chondrules may have formed from high-pressure collisions in the early solar system.
Water in the Earth's crust and upper mantle may not play such an important role as a lubricant of plate tectonics as previously assumed.
Prior to the Apollo Moon missions, scientists conjectured that the Moon would be extremely dry, that even below the surface of the Magnificent Desolation that little or no water would be present.
Geoengineering is a controversial and illegal practice that attempts to mitigate the forces of climate change on a grand scale. Many see this attempt to alter global climate via artificial means as a ‘quick fix’ with potential long-term negative effects.
Some meteorites found on Earth contain strikingly beautiful, translucent, olive-green crystals embedded in an iron-nickel matrix.
