Query: The remote detectability of Earth's biosphere through time and the
  importance of UV capability for characterizing habitable exoplanets   Thousands of planets beyond our solar system have been discovered to date,
dozens of which are rocky in composition and are orbiting within the
circumstellar habitable zone of their host star. The next frontier in life
detection beyond our solar system will be detailed characterization of the
atmospheres of potentially habitable worlds, resulting in a pressing need to
develop a comprehensive understanding of the factors controlling the emergence
and maintenance of atmospheric biosignatures. Understanding Earth system
evolution is central to this pursuit, and a refined understanding of Earth's
evolution can provide substantive insight into observational and interpretive
frameworks in exoplanet science. Using this framework, we argue here that UV
observations can help to effectively mitigate 'false positive' scenarios for
oxygen-based biosignatures, while 'false negative' scenarios potentially
represent a significant problem for biosignature surveys lacking UV capability.
Moving forward, we suggest that well-resolved UV observations will be critical
for near-term volume-limited surveys of habitable planets orbiting nearby
Sun-like stars, and will provide the potential for biosignature detection
across the most diverse spectrum of reducing, weakly oxygenated, and oxic
habitable terrestrial planets.
