The search for evidence of extraterrestrial life in our Solar System is currently guided by our
understanding of terrestrial biology and its associated biosignatures. The observed …

Jupiter's moon Europa has a subsurface ocean, the chemistry of which is largely unknown.
Carbon dioxide (CO2) has previously been detected on the surface of Europa, but it was not …

The surface and internal structure of Ceres show evidence of a global process of aqueous
alteration, indicating the existence of an ocean in the past. However, it is not clear whether …

Many habitable zone (HZ) exoplanets are expected to form with water mass fractions higher
than that of the Earth. For rocky exoplanets with 10–1000× Earth's H 2 O but without H 2, we …

The aim of this chapter is to describe available evidence for the existence of relict ocean
worlds. The focus is on Ceres as a clear example of such a world as indicated by the results …

Inspired by the recent results of the Dawn mission, thermodynamic models of rock alteration
and brine evaporation have been used to help understand the conditions under which water …

The spectral properties of anhydrous carbonates and nitrates are dominated by strong,
sharp vibrational bands due to the CO32− and NO3− anions observed as absorption bands …

This letter reports the first JWST spectroscopy of a white dwarf debris disc, giving a
preliminary assessment of the salient features, and recommendations for future …

Ceres, the only dwarf planet in the inner Solar System, appears to be a relict ocean world.
Data collected by NASA's Dawn spacecraft provided evidence that global aqueous …

The surface mineralogy of dwarf planet Ceres appears to be dominated by products of rock–
fluid interactions, such as phyllosilicates—some of which are NH4-bearing—and …
