Shapes and Colors That Transcend Scale

@ESA-CAVES just tweeted another pair of Earth and space images. One is Supernova remnant W49B. The other is an unidentified benthic colonial organism. The similarities in color and shape are undeniable.

Solar twins and analogs are fundamental in the characterization of the Sun's place in the context of stellar measurements, as they are in understanding how typical the solar properties are in its neighborhood.
