'Bathtub ring' hints at ancient Martian ocean

Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet's surface. The research was conducted by former Caltech postdoctoral ...

Between eternal night and day, the faces of two cousins of Earth

An international team including the University of Bern (UNIBE) and the University of Geneva (UNIGE), members of the National Center of Competence in Research PlanetS, has succeeded in mapping the climate of rocky exoplanets ...

How plants could betray themselves across the galaxy

Here's a thought experiment. Imagine looking at Earth from a distant star system, armed with a powerful telescope capable of capturing its reflected light. Could you tell the planet was alive? The answer, remarkably, might ...
