Martian moons have a common ancestor
Martian moons have a common ancestor
Phobos and Deimos are the remains of a larger Martian moon that was disrupted between 1 and 2.7 billion years ago, say researchers from the Institute of Geophysics at ETH Zurich and the Physics Institute at the University of Zurich. They reached this conclusion using computer simulations and seismic recordings from the InSight Mars mission.

On the quest for other earths
On the quest for other earths
An international research team with members from ETH has developed a new method for directly imaging smaller planets in the habitable zone of a neighbouring star system. This opens up new possibilities in the search for extraterrestrial life. In the search for planets capable of sustaining life, an international research team with members from ETH has taken a significant step forward.

CHEOPS finds unique planetary system
CHEOPS finds unique planetary system
The CHEOPS space telescope detects six planets orbiting the star TOI-178. Five of the planets are in a harmonic rhythm despite very different compositions. This result challenges our understanding of the formation and evolution of planetary systems. Musical notes that sound pleasant together can form a harmony.

Solar System formation in two steps
Solar System formation in two steps
Why are the planets of the inner Solar System dry and rocky, but the outer ones are not? An international team of researchers with participation of the University of Zurich discovered that a two-step formation process of the planets can explain the chronology and split in volatiles like water and isotope content of the inner and outer Solar System.

TRAPPIST-1's 7 Rocky Planets May Be Made of Similar Stuff
TRAPPIST-1’s 7 Rocky Planets May Be Made of Similar Stuff
The TRAPPIST-1 star is home to the largest batch of roughly Earth-size planets ever found outside our solar system. An international study involving researchers from the Universities of Bern, Geneva and Zurich now shows that the exoplanets have remarkably similar densities, which provides clues about their composition.

How our planets were formed
How our planets were formed
Terrestrial planets versus gas and ice giants: A new theory explaining why the inner solar system is so different to the outer regions runs counter to the prevailing wisdom. The theory was proposed by an international research group with ETH Zurich's participation. Mercury, Venus, Earth and Mars in the inner solar system are relatively small, dry planets, unlike Jupiter, Saturn, Uranus and Neptune in the outer regions, planets that contain much greater quantities of volatile elements.
