PSR B1257+12
PSR B1257+12 est un système spécial pour plusieurs raisons. Tout d’abord, l’étoile centrale, découverte par Aleksander Wolszczan en 1990 [1] et nommée Lich depuis décembre 2015 [2], est un pulsar. Même si Lich est 1,4 fois plus massif que le Soleil, son rayon n’est que de 10 kilomètres ! Ensuite, ce système fut le premier […]

It’s confirmed, Proxima b has three suns
A team of astronomers including Christophe Lovis, member of PlanetS, confirmed in a press release distributed by ESO that Proxima is gravitationally bound to its neighbors Alpha Centauri A and B. Since the discovery of Proxima in 1915 its proximity in the sky with Alpha Centauri and the similarity of their distance to the Sun […]

Education and outreach
Dear Reader, Many of you probably remember some privileged moments in your youth when you had a special encounter with science and perhaps thought, be it only for a short moment, that this could be something fun to do in life. Hard to predict what triggers these moments, perhaps reading a book, visiting a museum, […]

Study and play with real data
What’s more motivating for a student than to participate in research and perhaps make a real discovery. This is what the University of Geneva proposes in its MOOC (Massive Online Open Course) on exoplanets, a MOOC which at its first broadcast in 2015 met a huge success as more than 20’000 people attended this course […]

«Our telescope in Mexico is really filling a gap»
Brice-Olivier Demory is looking for earth-sized, potentially habitable exoplanets. Part of his research strategy is building a telescope in Mexico. Since August 2016, the 36 year old astronomer has been professor at the Center for Space and Habitability (CSH) of the University of Bern. His professorship is sponsored by the Swiss National Science Foundation (SNSF). […]

Spectacular images of Mars
«We saw Hebes Chasma at 2.8 metres per pixel. That’s a bit like flying over Bern at 15’000 kilometres per hour and simultaneously getting sharp pictures of cars in Zurich,» says Nicolas Thomas, principal investigator of the Mars camera CaSSIS and Director of the Physics Institute at the University of Bern. The Bernese instrument made […]

Research highlights
In modern astronomy researchers not only observe celestial objects, but also build them in computers and follow their evolution over time. These simulations reveal exciting new insights that – of course – have to be validated by observations. In the last few weeks, members of PlanetS published new results about comets, giant planets and earth-sized […]

Observing in La Silla logbook
The cliché of the astronomer spending all his/her time the eye behind his/her telescope, looking to the sky, is outdated. Most of the life of the current astronomer is spent behind the screen of a computer. However there are still times where he/she goes to observe, in some remote place like La Silla observatory in […]
