The next generation of ground and space-based telescopes will image habitable planets around nearby stars. A growing literature describes how to characterize such planets with spectroscopy, but less consideration has been given to the usefulness of planet colors. Here, we investigate whether potentially Earth-like exoplanets could be identified using UV-visible-to-NIR wavelength broadband photometry (350-1000 nm). Specifically, we calculate optimal photometric bins for identifying an exo-Earth… 
High-resolution Spectra for a Wide Range of Habitable Zone Planets around Sun-like Stars
The search for life in the universe is currently focused on Earth-analog planets. However, we should be prepared to find a diversity of terrestrial exoplanets not only in terms of host star but also
Color Classification of Extrasolar Giant Planets: Prospects and Cautions
Atmospheric characterization of directly imaged planets has thus far been limited to ground-based observations of young, self-luminous, Jovian planets. Near-term space- and ground- based facilities
The Direct Imaging Search for Earth 2.0: Quantifying Biases and Planetary False Positives
Direct imaging is likely the best way to characterize the atmospheres of Earth-sized exoplanets in the habitable zone of Sun-like stars. Previously, Stark et al. (2014, 2015, 2016) estimated the
The Pale Orange Dot: The Spectrum and Habitability of Hazy Archean Earth
TLDR
Coupled climate-photochemical-microphysical simulations demonstrate that hazes can cool the planet's surface by about 20 K, but habitable conditions with liquid surface water could be maintained with a relatively thick haze layer even with the fainter young Sun, and find that optically thicker hazes are self-limiting due to their self-shielding properties, preventing catastrophic cooling of the planet.
Color classification of Earth-like planets with machine learning
Atmospheric characterization of directly imaged exoplanets is currently limited to Giant planets and Mini-Neptunes. However, upcoming ground-based Extremely Large Telescopes (ELTs) and space-based
A Catalog of Spectra, Albedos, and Colors of Solar System Bodies for Exoplanet Comparison.
TLDR
This catalog provides a baseline for comparison of exoplanet observations to 19 bodies in the authors' own solar system, which can assist in the prioritization of ex planetets for time intensive follow-up with next-generation extremely large telescopes and space-based direct observation missions.
On the Utility of Transmission Color Analysis i: Differentiating Super-Earths and Sub-Neptunes
The majority of exoplanets found to date have been discovered via the transit method, and transmission spectroscopy represents the primary method of studying these distant worlds. Currently, in-depth
Earth as an Exoplanet
Earth is the only planet known to harbor life and, as a result, the search for habitable and inhabited planets beyond the Solar System commonly focuses on analogs to our planet. However, Earth's
Identifying Exo-Earth Candidates in Direct Imaging Data through Bayesian Classification
TLDR
A Bayesian method is presented for estimating the likelihood that any directly imaged extrasolar planet is a true exo-Earth candidate by interpreting the planet's apparent magnitude and separation in light of existing exoplanet statistics.
How to Characterize Habitable Worlds and Signs of Life
The detection of exoplanets orbiting other stars has revolutionized our view of the cosmos. First results suggest that it is teeming with a fascinating diversity of rocky planets, including those in

Remote sensing of planetary properties and biosignatures on extrasolar terrestrial planets.
TLDR
It is found that both the mid-IR and the visible to near-IR wavelength ranges offer valuable information regarding biosignatures and planetary properties; therefore both merit serious scientific consideration for TPF and Darwin.
Biosignatures from Earth-like planets around M dwarfs.
TLDR
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.
First light of the Gemini Planet Imager
TLDR
Observations ofBeta Pictoris clearly detect the planet, Beta Pictoris b, in a single 60-s exposure with minimal postprocessing, and fitting the Keplerian orbit of Beta Pic b using the new position together with previous astrometry gives a factor of 3 improvement in most parameters over previous solutions.

TLDR
M star planets could be a half to a tenth as productive as Earth in the visible, but exceed Earth if useful photons extend to 1.1 microm for anoxygenic photosynthesis, and under water, organisms would still be able to survive ultraviolet flares from young M stars and acquire adequate light for growth.
