What the TRAPPIST-1 planets could look like
Researchers at the University of Bern are providing the most precise calculations so far of the masses of the seven planets around the star TRAPPIST-1. From this, new findings are emerging about their density and composition: All TRAPPIST-1 planets consist primarily of rock and contain up to five percent water. This is a decisive step […]

Orbital mayhem around a red dwarf
Astronomers members of PlanetS, discovered that the GJ436b, nicknamed “the comet-like exoplanet” because it evaporates like a comet, follows a very special elliptical orbit over the poles of its star. In the collective imagination, planets of a solar system all circle around their star, in the same plane that is also the equatorial plane of […]

Astronomy in your wallet
There is a good chance that you are carrying 51 Pegasi around with you. The name of the star, around which the Geneva astronomers Michel Mayor and Didier Queloz discovered a planet in 1995, is on the new Swiss 20 franc banknote. In addition, there is a ten-digit number – an example of Swiss banking […]

A visit of the ice lab
What do the images of Mars, Comet Chury or other celestial bodies really show? For a reliable answer researchers at the University Bern study the optical properties of dust-ice mixtures that are analogs of planetary or cometary surfaces. Have a look at their laboratory.
