Frontiers in Astronomy and Space Sciences, 2021 In the search for life on other planets, the presence of photosynthetic surface vegetation may be detectable from the colors of light it reflects. On the modern Earth, this spectral reflectance is characterized by a steep increase in reflectance between ...

Oxygen False Positives on Habitable Zone Planets Around Sun‐Like Stars
AGU Advances, 2021 Oxygen is a promising exoplanet biosignature due to the evolutionary advantage conferred by harnessing starlight for photosynthesis, and the apparent low likelihood of maintaining oxygen‐rich atmospheres without life.

The Coming Emptiness: On the Meaning of the Emptiness of the Universe in Natural Philosophy
Philosophies, 2018 The cosmological relevance of emptiness—that is, space without bodies—is not yet sufficiently appreciated in natural philosophy. This paper addresses two aspects of cosmic emptiness from the perspective of natural philosophy: the distances to
