White Paper on Phototrophic Biosignatures: Research Priorities for the Search for Life on Other Worlds
Nancy Y. Kiang, Christopher Gisriel, Robert E. Blankenship +32
Photosynthesis is of prime interest in the telescopic search for life beyond the Solar System, because, on Earth, oxygenic photosynthesis produces two strong "biosignatures," globa…
Wavelength Requirements for Life Detection via Reflected Light Spectroscopy of Rocky Exoplanets
Joshua Krissansen-Totton, Anna Grace Ulses, Maxwell Frissell +21
Searching for signs of life is a primary goal of the Habitable Worlds Observatory (HWO). However, merely detecting oxygen, methane, or other widely discussed biosignatures is insuf…
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…
