An article published in the journal “Nature” describes a new research on the famous white spots in the dwarf planet Ceres’ Occator Crater. According to a team led by Maria Cristina De Sanctis, INAF – IAPS, the most abundant mineral is sodium carbonate. It’s a surprising result because that’s a salt that on Earth is abundant in hydrothermal sources and this raises the possibility of the presence of liquid water in Ceres underground.

An article published in the journal “Earth and Planetary Science Letters” describes a research on the possible link between the primordial bombardment of meteorites on Earth and the emergence of life forms. According to a team of researchers directed by Simone Marchi of the Southwest Research Institute in Boulder, Colorado, USA, the meteorites that struck Earth during its first billion years of life created a greenhouse effect sufficient to maintain the water in its liquid state, allowing the emergence of life.

An article published in the journal “Proceedings of the National Academy of Sciences” (PNAS) describes the unexpected discovery of a mineral called tridymite by the Mars Rover Curiosity in Gale Crater on Mars. The analysis of a sample from a rock called Buckskin revealed the presence of tridymite, which on Earth forms as a result of much more intense volcanic activity than that assumed esisted in the past on Mars.

An article about to be published in the journal “Geophysical Research Letters” boosts the theory of the existence of an underground ocean of liquid water on Pluto. An analysis of data collected by NASA’s New Horizons space probe during its July 14, 2015 flyby carried out by Noah Hammond, graduate student at Brown University, Providence, Rhode Island, USA, offers some clues to support this amazing possibility.
