Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

The widespread presence of ribonucleic acid (RNA) catalysts and cofactors in the Earth′ s
biosphere today suggests that RNA was the first biopolymer to support Darwinian evolution …

The HITRAN database is a compilation of molecular spectroscopic parameters. It was
established in the early 1970s and is used by various computer codes to predict and …

Geological evidence shows that ancient Mars had large volumes of liquid water. Models of
past hydrogen escape to space, calibrated with observations of the current escape rate …

One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

The search for life in the Universe is a fundamental problem of astrobiology and modern
science. The current progress in the detection of terrestrial-type exoplanets has opened a …

Reconciling the geology of Mars with models of atmospheric evolution remains a major
challenge. Martian geology is characterized by past evidence for episodic surface liquid …

terrestrial exoplanet evolution with the James Webb Space Telescope (JWST) and ground …

The TRAPPIST-1 system is the first transiting planet system found orbiting an ultracool dwarf
star. At least seven planets similar in radius to Earth were previously found to transit this host …

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 …
