Example Bioverse simulation of a survey to characterize Earth-sized planets in the HZ. This simulation used an 8m diameter telescope observing at λ= 550nm. This figure shows all rocky planets

Earth-like and super Earth planet candidates from (5) are shown in the effective temperature – instellation flux plane. Conservative and optimistic Habitable zones as defined in (5) are shown as

Schematic of the TRAPPIST-1 planetary system. The seven known planets are shown orbiting the central star. The semi-transparent green annulus marks the optimistic habitable zone, which contains planets e, f,

A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. Taken from a rock named “Cheyava Falls”

Rocks in the Bright Angel Formation. NASA’s Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover’s mast.
