Left panel: Original L-band detection of CC1 in Close et al. (2025a). Middle panel: New H-band detection of WISPIT 2c following RDI. We show a confined annulus that was used

Chloroplasts/kleptoplasts are shown in green, and pyrenoids are shown in yellow. a R. viridis ingests whole cells of a specific Tetraselmis strain by phagocytosis (ingestion event), typically consuming them within

A schematic diagram of the hycean Lotka-Volterra model we implement in this work. The schematic shows how various parameters in our model are connected in a vertical, one-dimensional water column.

Paleopoles based on averages of sample Virtual Geomagnetic Poles (VGPs) rather than site VGPs. In this treatment, sample H component directions are each treated as sites that sample the field

A synthesized false color image of Venus using 283-nm and 365-nm images taken by UVI. Images are colorized as follows: 283 nm → blue; 365 nm → red; mixture of

The volume mixing ratios of key gases in the Hycean and sub-Neptune atmospheres, averaged across 0.1 – 10−5 bar to represent the expected abundances of photochemical products probed by transmission
