Virtual Planetary Laboratory explore the distribution of habitable worlds in the universe. The VPL team studies the effects of galactic, stellar, and planetary environments on planetary habitability. Task D incorporates VPL researchers from diverse and interdisciplinary fields who use laboratory work combined with chemical and climate models to study the impact of life on its environment. In addition, the interactions between the biosphere, planet, and host star are explored to determine how they can influence detectable biosignatures. In the final task, the VPL scientists observe our Solar System and extrasolar planets. The goal of this task is to develop astronomical and remote-sensing retrieval
