Snapshots show planetary seeds’ growth and migration from two rings of material. This simulation comes from our M6T2 scenario. The top-left panel shows the starting time of the simulation. The time of each snapshot is shown on the bottom-left of each panel. The color of each dot corresponds to the water mass fraction of each planetary seed. We plot planetesimal and pebble isolation masses with dotted and dashed lines, respectively. The planetesimal isolation mass is obtained by extrapolating the initial surface density of the inner planetesimal disk. The vertical blue dashed line shows the location of the water condensation line. The blue solid line is the boundary of the inward and outward migration where the migration torque is zero. -- astro-ph.EP

Illustration of the planet at orbital quadrature (phase 1.25) and the red/blue shifted velocity and day/night components. At this phase, the planet is red-shifted from the orbital velocity, the dayside emission of the planet is blueshifted from winds and rotation while the fainter night-side is redshifted from winds and rotation. -- astro-ph.EP

Equivalences between categories in naturally occurring Biological Evolution and the stepwise abstraction hierarchy of synthetic biology based on Andrianantoandro et al. (2006). Note the match among the three central classes but the divergence at the left and right sides. Genuine biological functionality starts in proto-organs/devices, although it is preceded by the accumulation or capture of molecular assemblies/parts of lower complexity. Note that in certain cases, organisms might become organs as in the case of mitochondria, and probably systems can act as modules of a higher level system. -- Microlife via PubMed

Artist’s impression of the simulations conducted in this research. Jupiter (lower left) has a strong magnetic field which creates a cavity in its circumplanetary disk. Saturn (upper right) lacks a strong magnetic field so its circumplanetary disk evolves without a cavity. Credit: Yuri I. Fujii/L-INSIGHT [Kyoto University], Illustrator: Shinichiro Kinoshita

Several key access “windows” provide entry points to the crustal biosphere: 1 Hydrothermal vents at mid-ocean ridges (MORs), featuring both diffuse and focused high-temperature flows (up to ~400°C) and event plumes associated with seafloor eruptions; 2 Warm water seeps (
