Snowball Earth Might Be Slushy

Imagine a world without liquid water just solid ice in all directions. It would certainly not be a place that most life forms would like to live.

We present a comprehensive study of the abundance of carbon dioxide in exoplanetary atmospheres.

Considerable progress has been made in recent years in observations of atmospheric signatures of giant exoplanets, but processes in rocky exoplanets remain largely unknown due to major challenges in observing small planets.

Geological activity is thought to be important for the origin of life and for maintaining planetary habitability. We show that transient sulfate aerosols could be a signature of exoplanet volcanism, and therefore a geologically active world.

We introduce a novel Earth-like planet surface temperature model (ESTM) for habitability studies based on the spatial-temporal distribution of planetary surface temperatures.

Astrophysical ionizing radiation events have been recognized as a potential threat to life on Earth, primarily through depletion of stratospheric ozone and subsequent increase in surface-level solar ultraviolet radiation.

A new study is helping to answer a longstanding question that has recently moved to the forefront of earth science: Did our planet make its own water through geologic processes, or did water come to us via icy comets from the far reaches of the solar system?

A team of scientists using NASA's Hubble Space Telescope has made the most detailed global map yet of the glow from a planet orbiting another star, revealing secrets of air temperatures and water.

The recent discoveries of terrestrial exoplanets and super Earths extending over a broad range of orbital and physical parameters suggests that these planets will span a wide range of climatic regimes.

Understanding the atmosphere's composition during the Archean eon is a fundamental issue to unravel ancient environmental conditions.
