Left: The known exoplanet population (divided into two bins of masses above and below 10 Earth masses) as a function of their semi-major axis and of the central stellar mass.

A cosmic shoreline dividing exoplanets (errorbars) and Solar System planets (squares) with any type of atmosphere or global surface volatiles (blue symbols, Ai = 1) from those without (brown symbols,

Binned Kepler photometry (blue dots) of the KOI population which both exists above the period-radius valley and below the H2 atmospheric evaporation limit shown in Figure 4. Overlaid is a

Modelled planetary bulk-density over time. The initial hydrogen inventory of each bulk-density evolution track is shown by the line colour. Blue/green shaded regions are reference densities for a planet of

Pentameric architecture of CryoRs and unusual central channel. (A) Overall view of the CryoR1 pentamer in detergent micelles and nanodiscs. (B) View at the CryoR1 pentamer from the cytoplasmic side.

Example exoatlas visualization placing the first discovered transiting exoplanet HD209458b in context with other transiting exoplanets and the eight major Solar System planets. Errorbars use a color intensity that scales
