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

Finding life on exoplanets from telescopic observations is an ultimate goal of exoplanet
science. Life produces gases and other substances, such as pigments, which can have …

A key legacy of the recently launched the Transiting Exoplanet Survey Satellite (TESS)
mission will be to provide the astronomical community with many of the best transiting …

The field of exoplanet atmospheric characterization has recently made considerable
advances with the advent of high-resolution spectroscopy from large ground-based …

Abstract The Habitable Worlds Observatory Preliminary Input Catalog (HPIC) is a list of∼
13,000 nearby bright stars that will be potential targets for the Habitable Worlds Observatory …

Our generation could realistically be the one to discover evidence of life beyond Earth. With
this privileged potential comes responsibility. The magnitude of the question of whether we …

The habitable zone (HZ) is the circular region around a star (s) where standing bodies of
water could exist on the surface of a rocky planet. Space missions employ the HZ to select …

Planets similar to Earth but slightly more irradiated are expected to enter into a runaway
greenhouse state, where all surface water rapidly evaporates, forming an optically thick H 2 …

Recently postulated mechanisms and models can help explain the enduring 'Gaia'puzzle of
environmental regulation mediated by life. Natural selection can produce nutrient recycling …

Future NASA concept missions that are currently under study, like the Habitable Exoplanet
Imaging Mission (HabEx) and the Large Ultra-violet Optical Infra Red Surveyor, could …
