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.

Thanks to the James Webb Space Telescope, an international team including scientists is building a complete picture of the atmosphere of the planet WASP-39b. The James Webb Space Telescope (JWST) and its unparalleled images of our Universe offer us a new first: by combining several instruments, it draws a molecular and chemical portrait of the atmosphere of the exoplanet WASP-39b.

With the use of a precision experiment developed at the University of Bern, an international research team has succeeded in significantly narrowing the scope for the existence of dark matter. The experiment was carried out at the European Research Neutron Source at the Institute Laue-Langevin in France, and makes an important contribution to the search for these particles, of which little remains known.

A research team supported by the SNSF and including scientists from the UNIGE has studied the particular properties of the star Gamma Columbae. It is believed to be a binary star whose core has been exposed. A bright star visible to the naked eye, but until recently a star that was of no particular interest to scientists.

Following two large meteorite impacts on Mars, researchers have observed, for the first time, seismic waves propagating along the surface of a planet other than Earth. The data from the marsquakes was recorded by NASA's InSight lander and analysed at ETH Zurich in collaboration with the InSight Science Team.

Until now, Mars has been generally considered a geologically dead planet. An international team of researchers led by ETH Zurich now reports that seismic signals indicate vulcanism still plays an active role in shaping the Martian surface. Why study the terrestrial neighbour? Exploring Earth's planetary neighbours is no easy task.

The spectrograph developed by the UNIGE has enabled the discovery of the heaviest element ever detected in the atmosphere of a planet outside the solar system. An international team including researchers from the University of Geneva and the National Centre of Competence in Research (NCCR) PlanetS has detected the heaviest element ever found in the atmosphere of an exoplanet: barium.

Astronomical observations from ground-based telescopes are sensitive to local atmospheric conditions. Anthropogenic climate change will negatively affect some of these conditions at observation sites around the globe, as a team of researchers led by the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS report.

The Swiss space telescope CHEOPS will celebrate its 1000th day in orbit around the Earth on Tuesday 13 September. Its excellent condition will allow it to remain active for several more years. After 1000 days in orbit around the Earth, the CHEOPS space telescope shows almost no signs of wear. Under these conditions, it could continue to reveal the fascinating details of many exoplanets for many years to come.

An international research team, with the participation of the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS, discovered two "super-Earth" exoplanets. One is located at just the right distance from its star to potentially hold liquid water on its surface. Most of the planets that have been discovered around other stars - also known as exoplanets - are bad candidates for life as we know it.

With the help of artificial intelligence, an international research team led by ETH Zurich has explored the Moon's permanently shadowed regions. The information they have obtained about the area's surface properties will help to identify suitable locations for future lunar missions. It was 1972 when the last humans landed on the Moon.

The new space telescope has revealed the presence of carbon dioxide on the gas giant WASP-39b. A first in which the UNIGE and UNIBE participated. Launched at the end of 2021 by NASA, with the collaboration of the European Space Agency (ESA) and the Canadian Space Agency (CSA), the James-Webb Space Telescope has delivered an exceptional first scientific result: for the first time, CO2 has been clearly detected in the atmosphere of WASP-39b, a planet located outside the solar system.

The James Webb Space Telescope delivers a sensation right away with its first scientific result: for the first time, CO2 has been conclusively detected in the atmosphere of a planet outside the solar system. Researchers from the University of Bern, the University of Geneva and the National Centre of Competence in Research (NCCR) PlanetS are involved in the study.

Researchers from ETH Zurich discover the first definitive proof that the Moon inherited indigenous noble gases from the Earth's mantle. The discovery represents a significant piece of the puzzle towards understanding how the Moon and, potentially, the Earth and other celestial bodies were formed. Humankind has maintained an enduring fascination with the Moon.

An international research team reveals for the first time the origin of neutrinos, elementary particles that reach our planet from the depths of the Universe. Highly energetic and difficult to detect, neutrinos travel billions of light years before reaching our planet. Although it is known that these elementary particles come from the depths of our Universe, their precise origin is still unknown.

On 11 July, NASA published the first image taken by the James Webb Space Telescope. ETH Zurich Astrophysicist, Adrian Glauser was also involved in the construction of one of the telescope's measuring instruments. In an interview, he explains what he thought and felt when he saw the image. NASA has just published a first, spectacular image of the James Webb Space Telescope (JWST).

An international research team led by ETH Zurich proposes a new theory for the Earth's formation. It may also show how other rocky planets were formed. Although the Earth has long been studied in detail, some fundamental questions have still to be answered. One of them concerns the formation of our planet, about whose beginnings researchers are still unclear.

A team of researchers led by the University of Bern has for the first time identified an unexpected richness of complex organic molecules at a comet. This was achieved thanks to the analysis of data collected during ESA-s Rosetta mission at comet 67P/Churyumov-Gerasimenko, also known as Chury. Delivered to the early Earth by impacting comets, these organics may have helped to kick-start carbon-based life as we know it.

Geneva, 4 July 2022. Ten years ago, on July 4 2012, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) announced the discovery of a new particle with features consistent with those of the Higgs boson predicted by the Standard Model of particle physics. The discovery was a landmark in the history of science and captured the world's attention.

NASA's Double Asteroid Redirection Test (DART) mission is the world's first full-scale planetary defense test against potential asteroid impacts on Earth. Researchers of the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS now show that instead of leaving behind a relatively small crater, the impact of the DART spacecraft on its target could leave the asteroid near unrecognizable.
