Detecting Land With Reflected Light Spectroscopy To Rule Out Waterworld O2 Biosignature False Positives
The search for life outside our solar system is at the forefront of modern astronomy, and telescopes such as the Habitable Worlds Observatory (HWO) are being designed to identify biosignatures.
Micro-Mirror-Devices (MMDs): A New Family of MOEMS for the Habitable World Observatory
We present a new program aimed at developing a new generation of micromirror devices specifically tailored for astronomical applications, multi-slit spectroscopy in particular.
Planet Earth in Reflected and Polarized Light: II. Refining Contrast Estimates for Rocky Exoplanets with ELT and HWO
The characterization of nearby rocky exoplanets will become feasible with the next generation of telescopes, such as the Extremely Large Telescope (ELT) and the mission concept Habitable Worlds Observatory (HWO).
Habitable Worlds Observatory Call for Endorsers And Feedback
The HWO Science Working Groups are excited to share draft science cases that will help shape the top-level science goals, instrument needs, and mission architecture for the Habitable Worlds Observatory […]
Continuous Habitable Zone Metric for Prioritizing Habitable Worlds Observatory Targets
Future direct imaging space telescopes, such as NASA’s Habitable Worlds Observatory (HWO), will be the first capable of both detecting and characterizing terrestrial exoplanets in the habitable zones (HZ) of […]
Clouds Can Enhance Direct Imaging Detection Of O2 And O3 On Terrestrial Exoplanets
Clouds are often considered a highly uncertain barrier for detecting biosignatures on exoplanets, especially given intuition gained from transit surveys.
Closeby Habitable Exoplanet Survey (CHES). IV. Synergy Between Astrometry and Direct Imaging Missions of the Habitable World Observatory for Detecting Earth-like Planets
The detection and characterization of habitable planets around nearby stars persist as one of the foremost objectives in contemporary astrophysics. This work investigates the synergistic integration of astrometric and direct […]
What If We Find Nothing? Bayesian Analysis Of The Statistical Information Of Null Results In Future Exoplanet Habitability And Biosignature Surveys
Future telescopes will survey temperate, terrestrial exoplanets to estimate the frequency of habitable (ηHab) or inhabited (ηLife) planets.
Polarized Signatures of the Earth Through Time: An Outlook for the Habitable Worlds Observatory
The search for life beyond the solar system remains a primary goal of current and near-future missions, including NASA’s upcoming Habitable Worlds Observatory (HWO).
