Raging winds on Mars

On Mars, dust devils and winds reach speeds of up to 160 km/h and are therefore faster than previously assumed: This shows a study by an international research team led by the University of Bern. The researchers analyzed images taken by the Bernese Mars camera CaSSIS and the stereo camera HRSC with the help of machine learning. The study provides a valuable data basis for a better understanding of atmospheric dynamics, which is important for better climate models and future Mars missions.

Artificial intelligence drives the discovery of new exoplanets

Researchers from NCCR PlanetS and CSH have developed an AI model capable of predicting the architecture of planetary systems and subsequently inferring the presence of yet-to-be-discovered planets. They use the so-called Transformer architecture which is the basis of the LLMs powering tools like ChatGPT.

WP involved in NASA mission to explore the heliosphere

WP is participating in the NASA Interstellar Mapping and Acceleration Probe mission (IMAP), which is due to be launched no earlier than 23.09.2025. IMAP is dedicated to exploring the outer limits of the heliosphere, the protective bubble of solar wind in which our solar system is located. The findings should revolutionize our understanding of interstellar space, space weather and the protective function of the heliosphere for Earth.

Moon under bombardment

Where does the Moon's exosphere come from? A TU Wien study, which the University of Bern ist taking part in, and uses real lunar rock, reveals that the erosive effect of solar wind ions on the Moon has been vastly overestimated.

Tidal forces from the Sun could have deformed cliffs on Mercury

A new study by researchers of the University of Bern shows that the hilly surface of Mercury could be influenced not only by the cooling and contraction of the planet, but also by the tidal forces of the Sun. Future analysis will draw on new data from the BepiColombo mission, which is currently on its way to Mercury. BepiColombo is a joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA). The University of Bern is involved with two instruments.

Slope Streaks on Mars - not a sign of water after all?

A new study led by the University of Bern and Brown University in the U.S. casts doubt on one of the most tantalizing clues that water might be flowing on present-day Mars. Researchers analyzed a global database of 500,000 streaks that occur on Martian slopes, concluding they're likely caused by dry processes.

Venus more tectonically alive than we thought

Several tectonic processes are occurring beneath the surface of Venus, according to a new study led by researchers from the University of Bern’s Center for Space and Habitability and NASA. They found that many of the numerous “coronae” scattered over Venus’ globe are associated with gravity field perturbations.

AI unveils: Meteoroid impacts cause Mars to shake

A study led by the University of Bern shows that impacts on Mars send seismic shockwaves farther and deeper than previously thought and many of the marsquakes recorded by the NASA InSight lander are caused by meteoroid impacts.

Rockfall Loctions on Mars

A team lead by Bernese researchers has used a neural network to identify 1383 rockfall sites on Mars. More than half of these were previously unknown. The discovery is also relevant for future Mars missions.

First detection of frost on the Solar System's tallest volcanoes on Mars

For the first time, water frost has been detected on the colossal volcanoes on Mars, which are the largest in the Solar System. The international team led by the University of Bern used high-resolution color images from the Bernese Mars camera, CaSSIS, onboard the European Space Agency's ExoMars Trace Gas Orbiter spacecraft.

Hints of a possible atmosphere around a rocky exoplanet

Researchers using the James Webb Space Telescope may have detected an atmosphere surrounding a rocky exoplanet 41 light-years from Earth. Brice-Olivier Demory, Professor of Astrophysics at the University of Bern was part of the international research team that just published the results in Nature.

DART impact might have reshaped Hera's target asteroid

ESA's Hera spacecraft for planetary defence is being prepared for a journey to the distant asteroid moon Dimorphos orbiting around its parent body Didymos. One of the first features Hera will look for is the crater left on Dimorphos by its predecessor mission DART, which impacted the asteroid to deflect its orbit.

Moon rocks with unique dust found

A research team led by the University of Münster, including CSH Fellow Valentin Bickel, studied the interaction of dust with boulders and discovered potentially anomalous rocks on the moon. Their findings were published in the Journal of Geophysical Research - Planets.

An astronomical waltz reveals a sextuplet of planets

An international collaboration between astronomers using the CHEOPS and TESS space satellites, including NCCR PlanetS members from the University of Bern and the University of Geneva, have found a key new system of six transiting planets orbiting a bright star in a harmonic rhythm. This rare property enabled the team to determine the planetary orbits which initially appeared as an unsolvable riddle.

Elusive planets play “hide and seek” with CHEOPS

With the help of the CHEOPS space telescope an international team of European astronomers managed to clearly identify the existence of four new exoplanets. Dr. Solène Ulmer-Moll of the Universities of Bern and Geneva, and Dr. Hugh Osborn of the University of Bern, exploited the unique synergy of CHEOPS and the NASA satellite TESS, in order to detect a series of elusive exoplanets.

Small asteroids are probably young

The impact experiment conducted on the asteroid Ryugu by the Japanese Hayabusa2 mission which took place two years ago resulted in an unexpectedly large crater. With the use of simulations, a team led by the University of Bern and the National Center of Competence in Research (NCCR) PlanetS has recently succeeded in gaining new insights from the experiment regarding the formation and development of asteroids. These insights are also important for the DART mission of NASA.

A pair of lonely planet-like objects born like stars

An international research team led by Dr. Clémence Fontanive from the CSH has discovered an exotic binary system composed of two young planet-like objects, orbiting around each other from a very large distance. Although these objects look like giant exoplanets, they formed in the same way as stars, proving that the mechanisms driving star formation can produce rogue worlds in unusual systems deprived of a Sun.

Liquifying a rocky exoplanet

A hot, molten Earth would be around 5% larger than its solid counterpart. This is the result of a study led by researchers at the University of Bern. The difference between molten and solid rocky planets is important for the search of Earth-like worlds beyond our Solar System and the understanding of Earth itself.

For the first time, two teams of researchers from the universities of Bern and Geneva, led by Profs. Drs. Kevin Heng and David Ehrenreich, respectively, have definitively discovered iron and titanium in the atmosphere of an exoplanet. The existence of these elements in gaseous form was theoretically predicted in a companion paper led by CSH Postdoc Dr. Daniel Kitzmann. The observational discovery paper was led by PlanetS Postdoc Dr. Jens Hoeijmakers.
