the science with zero confirmed subjects and infinite patience
means The scientific study of the possibility, origin, and nature of life beyond Earth — and what life's existence anywhere can teach us about life everywhere.
from Built from Greek pieces: astron, 'star,' biology, the study of life. The term gained traction in the 20th century alongside the space age, a younger sibling of 'exobiology,' coined by the geneticist Joshua Lederberg in the late 1950s. NASA's embrace of 'astrobiology' in the 1990s gave it institutional weight — a name for a field studying a subject it hasn't yet found.
