Astrobiology Expands: Interplanetary Habitable Zones, Panspermia, and the Quest for Technosignatures
To the point
Astrobiology now looks beyond Earth-like worlds to see where life could exist, how it might travel between planets, how stars and space chemistry shape habitability, how we might detect intelligent life through megastructures, and what space experiments reveal about microbes and life's building blocks, all while acknowledging big uncertainties that keep revising our ideas.
