Astrobiology & Origin of Life

The interdisciplinary science exploring the origins, evolution, and distribution of life in the universe — from prebiotic chemistry on early Earth to the search for biosignatures on exoplanets, extremophile survival limits, and the probability of habitable worlds beyond our solar system.

Astrobiology sits at the intersection of biology, chemistry, planetary science, and astronomy. It asks the most profound question in science: are we alone? By studying how life originated on Earth — from the Miller-Urey spark that synthesized amino acids to the extremophiles thriving in boiling acid — astrobiologists develop frameworks for recognizing life wherever it might exist.

These simulations let you calculate habitable zones around different star types, recreate prebiotic chemistry experiments, estimate the probability of habitable worlds using modern parameters, explore the survival boundaries of extremophile organisms, and analyze spectral biosignatures that future telescopes like the Habitable Worlds Observatory will search for in exoplanet atmospheres.
