ESPRESSO confirms the existence of an exo-Earth 4 light-years away
An international team of experts, including researchers from the NCCR PlanetS, has confirmed the existence of the Proxima b extrasolar planet using measurements from the Swiss-built ESPRESSO spectrograph. The existence of a planet the size of Earth around the closest star in the solar system, Proxima Centauri, has been confirmed by an international team of scientists […]

How we might search for life in the future
The “LIFE” mission, proposed by PlanetS researchers, could help answer questions about the habitability of our cosmic environment by employing a direct approach. When looking up at the sky at night, sooner or later the inevitable question arises: “Are we alone?” So far, science has not found the answer, even though it has been certain […]

Origin of two “cosmic diamonds” clarified
“Bennu” and “Ryugu” are two near-Earth asteroids with a diamond-like shape, the origin of which has long been a mystery. Now simulations of asteroid break-ups show how the special shape came about. The results could also help to better understand the processes involved in the formation of the Earth. Around four and a half billion […]

Otherworldly winds
A group of scientists led by the NCCR-PlanetS and the University of Geneva, investigated wind patterns of an exoplanet with extreme conditions. Their insights may also help us understand the atmospheres of other worlds. Including our own. Imagine you were looking down upon the Earth from space. Your task would be to discern the general […]

Scientists achieve simultaneous simulation of gravitation and magnetism of a protoplanetary disk
Researchers from the Universities of Zurich and Cambridge have succeeded for the first time in creating a single computer-simulated model that combines processes in the development of planets that were previously simulated separately. In their novel simulations on the “Piz Daint” supercomputer, they identified a new kind of friction mechanism that could solve a ubiquitous […]

Explore the universe from home with PlanetS
For weeks we have been spending most of our time at home. We are distancing ourselves from each other, trying to get the Corona crisis under control. That brings with it many challenges. Schools, for example, now often rely on online lessons. But that doesn’t work smoothly everywhere and in some places lessons are cancelled. […]

Living in the days of the Coronavirus is not easy. As many aspects of society shut down in an effort to slow down the progression of the virus, it is difficult to maintain scientific activities. No lectures or colloquia anymore, conferences and schools are cancelled, observatories are restricting operations… Business as usual is no more. […]

CHEOPS first check-up
After months of uncertainty about the launch date of the CHEOPS satellite, the launch date was finally set for December 17, 2019. A delegation from the Universities of Bern and Geneva were on hand on the scheduled date to attend this unique event in Swiss space history. Although the launch was delayed by 24 hours […]

Why Uranus and Neptune are different
The two outermost giant planets of the Solar system have similar masses but there are also striking differences. Researchers of the NCCR PlanetS at the University of Zurich have found an explanation for this long-standing unsolved mystery: Two different giant impacts could have had completely separate effects. Uranus and Neptune are the outermost planets of the Solar […]
