Venus and Earth are similar in bulk properties yet followed dramatically different climatic trajectories.
What if fog isn’t just misty air, but a living ecosystem?
Decades of study have hinted at the astrobiological potential of Venus’s cloud layers. This potential is often cast as stemming from the idea that the Venusian surface was clement in […]
The stratosphere’s highly hostile environment offers a unique and relatively accessible setting to evaluate extremophilic adaptation for extraterrestrial colonization. The accelerating pace of the Martian project has underscored the need […]
Magma ocean crystallisation sets up the early structure and long-term evolution of terrestrial planets. Recent seismic evidence signals the presence of a silicate layer at the base of Mars’ mantle.
With recent advances in exoplanet observational techniques enabling the discovery of increasingly smaller planets, a crucial question emerges in the search for habitable planets: how small can a planet be […]
A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered a major share of Earth’s water. A new study argues that the […]
The delivery of water to the inner Solar System rocky planets, including Earth, remains debated, as standard models assume that they formed from dry grains, inside the snowline of the […]
NASA’s Habitable Worlds Observatory (HWO) will search for biosignatures on Earth-like exoplanets using reflected light spectroscopy.
