The majority of stars in our galaxy are home to planets. The most abundant are the sub-Neptunes, planets between the size of Earth and Neptune. Calculating their density poses a problem for scientists ...

The ice giant classification is oversimplified, as Uranus and Neptune are still poorly understood,” meint Luca Morf des Universitats Zürich. Erörterung des schweizer Wissenschaftler sollte jedoch ...

For decades, scientists have believed that Uranus and Neptune are “ice giants,” planets made mostly of icy materials like water, ammonia and methane. But a new study from the University of Zurich and ...

Uranus and Neptune may not be the icy worlds we’ve long imagined. A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by ...

New models suggest Uranus and Neptune may hold far more rock than expected, raising questions about how these distant planets formed.

A team of researchers from the University of Zurich and the NCCR PlanetS is challenging our understanding of the solar system planets' interior. The composition of Uranus and Neptune, the two ...

If you look at our Solar System, there’s a sharp divide between the four rocky planets and the large “ice giants” of the outer Solar System, Uranus, and Neptune. The divide isn’t only a matter of ...
