One Hundred Years of Venus Polarimetry: PICSARR Observations of the Phase Curves
Jeremy Bailey, Daniel V. Cotton, Kimberly Bott +1
We report new high-precision observations of the polarization of light scattered from the atmosphere of Venus, made 100 years after the pioneering studies by Bernard Lyot. The new…
Imaging Venus-like Worlds: Spectral, Polarimetric, and UV Diagnostics for the Habitable Worlds Observatory
Stephen R. Kane, Kimberly M. Bott, Kenneth E. Goodis Gordon +15
Understanding planetary habitability requires a comparative approach that explores the divergent evolutionary outcomes of Earth and Venus. The Habitable Worlds Observatory (HWO) wi…
Detecting alien living worlds and photosynthetic life using imaging polarimetry with the HWO coronagraph
Svetlana Berdyugina, Lucas Patty, Jonathan Grone +10
Our Earth, being the only living planet that we know, provides us with clues that photosynthetic life-forms may be dominant on other exoplanets for billions of years. Spectropolari…
Polarized Signatures of the Earth Through Time: An Outlook for the Habitable Worlds Observatory
Kenneth E. Goodis Gordon, Theodora Karalidi, Kimberly M. Bott +5
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). However, resea…
