As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be photosynthesis, particularly photosynthesis that has evolved with a different parent star. We take previously simulated planetary atmospheric compositions for Earth-like planets around observed F2V and K2V, modeled M1V and M5V stars, and around the active M4.5V star AD Leo; our scenarios use Earth's atmospheric…

The Productivity of Oxygenic Photosynthesis around Cool, M Dwarf Stars

In the search for life around cool stars, the presence of atmospheric oxygen is a prominent biosignature, as it may indicate oxygenic photosynthesis (OP) on the planetary surface. On Earth, most

Planetary targets in the search for extrasolar oxygenic photosynthesis

Background: In the coming decades space telescopes will be constructed that will attempt to find the gaseous products of oxygenic photosynthesis, the most promising biosignatures of life, in the

Super-Earths, M Dwarfs, and Photosynthetic Organisms: Habitability in the Lab

These findings highlight the importance of simulating both the visible and FR light components of an M dwarf spectrum to correctly evaluate the photosynthetic performances of oxygenic organisms exposed under such an exotic light condition.

The Peak Absorbance Wavelength of Photosynthetic Pigments Around Other Stars From Spectral Optimization

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

Constraints on Aquatic Photosynthesis for Terrestrial Planets around Other Stars

Aquatic photosynthesis plays a major role in carbon fixation and O2 production on Earth. In this Letter, we analyze the prospects for oxygenic photosynthesis in aquatic environments on modern


We model the atmospheres and spectra of Earth-like planets orbiting the entire grid of M dwarfs for active and inactive stellar models with Teff = 2300 K to Teff = 3800 K and for six observed MUSCLES

Photosynthetic Fluorescence from Earthlike Planets around Sunlike and Cool Stars

Remote sensing of the Earth has demonstrated that photosynthesis is traceable as the vegetation red edge (VRE), which is a steep rise in the reflection spectrum of vegetation, and as solar-induced

Cryptic photosynthesis--extrasolar planetary oxygen without a surface biological signature.

The hypothetical cryptic photosynthesis worlds discussed here are Earth analogues that show detectable atmospheric biosignatures like the authors' own planet but do not exhibit a discernable biological surface feature in the disc-averaged spectrum.


Ongoing searches for exoplanetary systems have revealed a wealth of planets with diverse physical properties. Planets even smaller than the Earth have already been detected and the efforts of future

Photosynthesis in Hydrogen-Dominated Atmospheres

The evolution of methane-based photosynthesis is at least as likely as the evolution of anoxygenic photosynthesis on Earth and may support the development of complex life.



Constraints on Photosynthesis on Earth and Earth-Like Planets

. We discuss how the spectral mismatch between solar radiation at the Earth's surface and the two absorption maxima (440 and 680 nm) of the dominant chlorophyll pigments can be explained as an

Biosignatures from Earth-like planets around M dwarfs.

Coupled one-dimensional photochemical-climate calculations have been performed for hypothetical Earth-like planets around M dwarfs to determine which biosignature gases might be observed by a future, space-based telescope.

Detectability of Red-Edge-shifted Vegetation on Terrestrial Planets Orbiting M Stars

We have explored the detectability of exovegetation on the surface of a terrestrial planet orbiting an M star. The exovegetation is responsible for producing a pigment-derived surface signature that

Limits of photosynthesis in extrasolar planetary systems for earth-like planets.

Photosynthesis: Likelihood of Occurrence and Possibility of Detection on Earth-like Planets

Abstract Although there are considerable technical challenges to be overcome during this decade, the prospects for the detection of Earth-like planets (ELPs) orbiting nearby stars are encouraging. If

Ozone concentrations and ultraviolet fluxes on Earth-like planets around other stars.

Coupled radiative-convective/photochemical modeling was performed for Earth-like planets orbiting different types of stars and found that advanced life is theoretically possible on high-O(2) planets around F stars, but it is not obvious that it would evolve as it did on Earth.

A test for the search for life on extrasolar planets - Looking for the terrestrial vegetation signature in the Earthshine spectrum

We report spectroscopic observations (400 to 800nm, R = approx 100) of Earthshine in June, July and October 2001 from which normalised Earth albedo spectra have been derived. The resulting spectra

Spectral signatures of photosynthesis. I. Review of Earth organisms.

The "near-infrared (NIR) end" of the red edge to trend from blue-shifted to reddest for snow algae, temperate algae, lichens, mosses, aquatic plants, and finally terrestrial vascular plants is found.

Zones of photosynthetic potential on Mars and the early Earth

Detectability of planetary characteristics in disk-averaged spectra. I: The Earth model.

A spatially and spectrally resolved model of the Earth is developed and comparison between the data and model indicates that several atmospheric species can be identified in disk-averaged Earth spectra, and potentially detected depending on the wavelength range and resolving power of the instrument.
