In the coming years and decades, advanced space-and ground-based observatories will
allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially …

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

Earth has had oceans for nearly four billion years and Mars had lakes and rivers 3.5–3.8
billion years ago. However, it is still unknown whether water has ever condensed on the …

We present an improved estimate of the occurrence rate of small planets orbiting small stars
by searching the full four-year Kepler data set for transiting planets using our own planet …

We investigate a new class of habitable planets composed of water-rich interiors with
massive oceans underlying H 2-rich atmospheres, referred to here as Hycean worlds. With …

The ongoing discoveries of extra-solar planets are unveiling a wide range of terrestrial mass
(size) planets around their host stars. In this Letter, we present estimates of habitable zones …

Habitability is a widely used word in the geoscience, planetary science, and astrobiology
literature, but what does it mean? In this review on habitability, we define it as the ability of …

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 …

Context. In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M
dwarfs provide unique opportunities for characterising their atmospheres, as well as …

Radial velocity monitoring has found the signature of a Msini= 1.3M⊕ planet located within
the habitable zone (HZ) of Proxima Centauri. Despite a hotter past and an active host star …
