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…
Remote Sensing of Chiral Signatures on Mars
William Sparks, James H. Hough, Thomas A. Germer +2
We describe circular polarization as a remote sensing diagnostic of chiral signatures which may be applied to Mars. The remarkable phenomenon of homochirality provides a unique bio…
Detection of circular polarization in light scattered from photosynthetic microbes
William B. Sparks, James Hough, Thomas A. Germer +9
The identification of a universal biosignature that could be sensed remotely is critical to the prospects for success in the search for life elsewhere in the universe. A candidate…
