The 47 pages that link to Astrobiology, each with the reason it gives.

• Origin of lifeNarrower topic: Origin-of-life research supplies astrobiology with criteria for evaluating habitable worlds.

• Planetary habitabilityNarrower topic: Habitability frames astrobiology's search for environments where life could persist.

• ArchaeaNarrower topic: Extremophile archaea inform ideas about life's limits and possible extraterrestrial habitats.

• EuropaNarrower topic: Europa is a leading Solar System setting for investigating whether life can exist beyond Earth.

• Tidal heatingNarrower topic: Tidal heating can supply energy to subsurface environments beyond a star's habitable zone.
