Forming Mercury by Giant Impacts
The smallest planet in our Solar System has a large iron core. How come? According to the most popular theory, Mercury lost big parts of its rocky mantle in a collision. Alice Chau and her colleagues at the University of Zürich simulated different scenarios with a super computer. Their result: Forming Mercury by giant impacts […]

Connected to space
After a long tour through Europe, the CHEOPS satellite is back at Airbus Defence and Space Spain in Madrid. On its journey, it had to pass thermal-vacuum tests at Airbus facilities in Toulouse, mechanical vibration tests at RUAG Space in Zürich, and acoustic noise and electromagnetic compatibility tests at ESA’s technical centre in The Netherlands.

How the moons of Jupiter were formed
When astrophysicists of the NCCR PlanetS at the University of Zürich analyzed their computer simulations they were amazed: The formation of the moons of Jupiter happened much faster and later than previously believed. The researchers also found out that the satellites we see today are likely not the only moons that formed around the planet, […]

Tutorial: How to make nice and simple exoplanets artist’s impressions
By Thibaut Roger If you have ever read a press article about exoplanets, you certainly have already seen a nice artist’s impression illustrating it. Indeed, except for rare cases, we cannot see an exoplanet directly, we only see its effect on its host star. Even when we can use the method called direct imaging to […]

The Stuff that Planets Are Made of
Researchers of the NCCR PlanetS at the University of Zürich have analyzed the composition and structure of far-away exoplanets using statistical tools. Their analysis indicates whether a planet is earth-like, made up of pure rock or a water-world. The larger the planet, the more hydrogen and helium surround it. Is there a second Earth out […]
