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 the habitable zone. Even our closest star, Proxima Centauri, harbors a small planet in its habitable zone, Proxima b. With the next generation of telescopes, we will be able to peer into the atmospheres of rocky planets and get a glimpse into other worlds. Using our own planet and its wide range of… 

Color Catalogue of Life in Ice: Surface Biosignatures on Icy Worlds.

A spectra catalogue of life in ice to facilitate the search for extraterrestrial signs of life on icy worlds based on biota from Earth's icy environments is developed and is available online.

Risks for Life on Habitable Planets from Superflares of Their Host Stars

We explore some of the ramifications arising from superflares on the evolutionary history of Earth, other planets in the solar system, and exoplanets. We propose that the most powerful superflares

Habitability and Biosignatures of Hycean Worlds

We investigate a new class of habitable planets composed of water-rich interiors with massive oceans underlying H2-rich atmospheres, referred to here as Hycean worlds. With densities between those of

Past, present and future stars that can see Earth as a transiting exoplanet.

It is reported that 1,715 stars within 100 parsecs from the Sun are in the right position to have spotted life on a transiting Earth since early human civilization (about 5,000 years ago), with an additional 319 stars entering this special vantage point in the next 5, thousand years.

Biosignatures Search in Habitable Planets

The search for life has had a new enthusiastic restart in the last two decades thanks to the large number of new worlds discovered. The about 4100 exoplanets found so far, show a large diversity of

The White Dwarf Opportunity: Robust Detections of Molecules in Earth-like Exoplanet Atmospheres with the James Webb Space Telescope

The near-term search for life beyond the solar system currently focuses on transiting planets orbiting small M dwarfs, and the challenges of detecting signs of life in their atmospheres. However,

Which stars can see Earth as a transiting exoplanet?

Transit observations have found the majority of exoplanets to date. Spectroscopic observations of transits and eclipses are the most commonly used tool to characterize exoplanet atmospheres and will

Atmospheric characterization of terrestrial exoplanets in the mid-infrared: biosignatures, habitability, and diversity

Exoplanet science is one of the most thriving fields of modern astrophysics. A major goal is the atmospheric characterization of dozens of small, terrestrial exoplanets in order to search for

Detectability of Life Using Oxygen on Pelagic Planets and Water Worlds

The search for life on exoplanets is one of the grand scientific challenges of our time. The strategy to date has been to find (e.g., through transit surveys like Kepler) earthlike exoplanets in

Finding Signs of Life on Transiting Earthlike Planets: High-resolution Transmission Spectra of Earth through Time around FGKM Host Stars

The search for life in the universe mainly uses modern Earth as a template. However, we know that Earth’s atmospheric composition changed significantly through its geological evolution. Recent



Colors of extreme exo-Earth environments.

How filter photometry can serve as a first step in characterizing Earth-like exoplanets for an aerobic as well as an anaerobic atmosphere, thereby prioritizing targets to search for atmospheric biosignatures is explored.

The Habitability of Our Earth and Other Earths: Astrophysical, Geochemical, Geophysical, and Biological Limits on Planet Habitability

For life-forms like us, the most important feature of Earth is its habitability. Understanding habitability and using that knowledge to locate the nearest habitable planet may be crucial for our

The Hunt for Exomoons with Kepler (HEK). I. Description of a New Observational project

Two decades ago, empirical evidence concerning the existence and frequency of planets around stars, other than our own, was absent. Since that time, the detection of extrasolar planets from

Characterizing the purple Earth: Modelling the globally-integrated spectral variability of the Archean Earth

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

The Habitability of Proxima Centauri b: Environmental States and Observational Discriminants

1-D coupled climate-photochemical models are used to generate self-consistent atmospheres for several evolutionary scenarios, including high-O2, high-CO2, and more Earth-like atmospheres, with both oxic and anoxic compositions, and show that these modeled environments can be habitable or uninhabitable at Proxima Cen b's position in the habitable zone.

Habitable planets around the star Gliese 581

Radial velocity surveys are now able to detect terrestrial planets at habitable distance from M-type stars. Recently, two planets with minimum masses below 10 Earth masses were reported in a triple

Evolution of a habitable planet

The Habitability of Planets Orbiting M-dwarf Stars

Habitable zone lifetimes of exoplanets around main sequence stars.

The results show that exoplanet HD 85512b is no longer within the HZ, assuming it has an Earth analog atmosphere, and should be considered in future models of planetary habitability as setting an upper limit on the lifetime of any potential exoplanetary biosphere.

Habitability of Exomoons at the Hill or Tidal Locking Radius

Moons orbiting extrasolar planets are the next class of object to be observed and characterized for possible habitability. Like the host-planets to their host-star, exomoons have a limiting radius at
