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…
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…
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…
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…
Detectability Simulations of a NIR Surface Biosignature on Proxima Centauri b with Future Space Observatories
Connor O. Metz, Nancy Y. Kiang, Geronimo L. Villanueva +2
Telescope missions are currently being designed which will make direct imaging of habitable exoplanets possible in the near future, and studies are needed to quantify the detectabi…
Alternative Methylated Biosignatures I: Methyl Bromide, A Capstone Biosignature
Michaela Leung, Edward W. Schwieterman, Mary N. Parenteau +1
The first potential exoplanet biosignature detections are likely to be ambiguous due to the potential for false positives: abiotic planetary processes that produce observables simi…
The peak absorbance wavelength of photosynthetic pigments around other stars from spectral optimization
Owen R. Lehmer, David C. Catling, Mary N. Parenteau +2
In the search for life on other planets, the presence of photosynthetic vegetation may be detectable from the colors of light it reflects. On the modern Earth, this spectral reflec…
Claimed detection of PH in the clouds of Venus is consistent with mesospheric SO
Andrew P. Lincowski, Victoria S. Meadows, David Crisp +7
The observation of a 266.94 GHz feature in the Venus spectrum has been attributed to PH in the Venus clouds, suggesting unexpected geological, chemical or even biological proce…
Spectropolarimetry of primitive phototrophs as global surface biosignatures
William B. Sparks, M. Niki Parenteau, Robert E. Blankenship +5
Photosynthesis is an ancient metabolic process that began on the early Earth, offering plentiful energy to organisms that utilize it, to the extent that they can achieve global sig…
Exoplanet Biosignatures: Understanding Oxygen as a Biosignature in the Context of Its Environment
Victoria S. Meadows, Christopher T. Reinhard, Giada N. Arney +13
Here we review how environmental context can be used to interpret whether O2 is a biosignature in extrasolar planetary observations. This paper builds on the overview of current bi…
Exoplanet Biosignatures: A Review of Remotely Detectable Signs of Life
Edward W. Schwieterman, Nancy Y. Kiang, Mary N. Parenteau +15
In the coming years and decades, advanced space- and ground-based observatories will allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially habitab…
