How Many Exoplanets are Hiding in Dust?

What can exozodiacal dust, also called exozodi, teach astronomers about identifying Earth-like exoplanets? This is what a recently submitted NASA white paper—which highlights key findings from the annual Architecture Concept Review—hopes to address as a team of researchers discussed how exozodi orbiting within a star’s habitable zone (HZ) could interfere with detecting Earth-like exoplanets. This study has the potential to help scientists better understand observational constraints of observing Earth-like exoplanets and what improvements could be made for future telescopes and instruments to overcome these constraints.
