Circles denote the location of eDNA samples collected and preserved by the ESP onboard Surveyor during its ~4200-km transit over 29 days (June 10–July 9, 2021) from San Francisco to the Hawaiian Islands. Transit across oceanographic domains, from the California Current upwelling system to the North Pacific Subtropical Gyre, is represented by sea surface temperature (SST) from satellite remote sensing. Shown is the June 2021 average of multiscale ultra-high resolution (MUR) SST Analysis fv04.1, acquired from https://coastwatch.pfeg.noaa.gov/erddap/index.html.

Color phase curves (CPCs) for the sum of planets ’b’ and ’d’ in the Proxima Centauri system. The CPC is the ratio of the flux in the 21 µm to 12.8 µm JWST/MIRI filters, normalized to the stellar flux, with the median value subtracted from the normalized ratio. The CPCs are the sum of both planets, and are shown here for the 2027 visibility period for JWST (lighter when not visible). Two cases are shown: using a hot rock model for ’b’, and a GCM (see text). Planet ’d’ is modeled as a hot rock in both cases.
