The Building Materials For Water-rich Planets In The Early Solar System

Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These so-called […]

Spectral Properties Of Bright Deposits In Permanently Shadowed Craters On Ceres

Bright deposits in permanently shadowed craters on Ceres are thought to harbor water ice. However, the evidence for water ice presented thus far is indirect.

Marine Science Can Contribute to the Search for Extra-Terrestrial Life

Abstract: Life on our planet likely evolved in the ocean, and thus exo-oceans are key habitats to search for extraterrestrial life. We conducted a data-driven bibliographic survey on the astrobiology […]
