Mountain ranges, volcanoes, trenches, and craters are common on rocky bodies throughout the Solar System, and we might we expect the same for rocky exoplanets. With ever larger telescopes under […]

Galactic Effects on Habitability
The galactic environment has been suspected to influence planetary habitability in many ways. Very metal-poor regions of the Galaxy, or those largely devoid of atoms more massive than H and […]

Habitability of Exoplanet Waterworlds
We model the evolution of ocean temperature and chemistry for rocky exoplanets with 10-1000 times Earth’s H2O but without H2, taking into account C partitioning, high-pressure ice phases, and atmosphere-lithosphere […]

Subsurface Exolife
We study the prospects for life on planets with subsurface oceans, and find that a wide range of planets can exist in diverse habitats with relatively thin ice envelopes We […]

Four Earth-sized Planets Detected Orbiting tau Ceti
A new study by an international team of astronomers reveals that four Earth-sized planets orbit the nearest sun-like star, tau Ceti, which is about 12 light years away and visible […]

Two Possible Planets In Tau Ceti's Habitable Zone
The removal of noise typically correlated in time and wavelength is one of the main challenges for using the radial velocity method to detect Earth analogues. We analyze radial velocity […]

Implications of Tides for Life on Exoplanets
As evident from the nearby examples of Proxima Centauri and TRAPPIST-1, Earth-sized planets in the habitable zone of low-mass stars are common. Here, we focus on such planetary systems and […]

A New Search for Extrasolar Planets Around Barnard's Star
The National Science Foundation’s Arecibo Observatory and the Planetary Habitability Laboratory of the University of Puerto Rico at Arecibo joined the Red Dots project in the search for new planets […]

Exoplanets and SETI
The discovery of exoplanets has both focused and expanded the search for extraterrestrial intelligence. The consideration of Earth as an exoplanet, the knowledge of the orbital parameters of individual exoplanets, […]

Searching for Exoplanets Using Artificial Intelligence
In the last decade, over a million stars were monitored to detect transiting planets. Manual interpretation of potential exoplanet candidates is labor intensive and subject to human error, the results […]
