An international team led by UNIGE has discovered a massive, Milky Way-like spiral galaxy that formed just 1 billion years after the Big Bang, revealing an unexpectedly mature structure in the An international team led by the University of Geneva has discovered the most distant spiral galaxy candidate known to date.

A team from the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS has developed a machine learning model that predicts potential planetary systems with Earth-like planets. The model could significantly accelerate and thus revolutionize the future search for habitable planets in the universe.

An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models. For a long time, scientists thought that only actively star-forming galaxies should be observed in the very early Universe.

Using TESS and ESPRESSO, the high-precision spectrograph operated by the University of Geneva, an international team has discovered a new super-Earth 218 light-years away. An international team, including researchers from the University of Geneva and the National Centre of Competence in Research PlanetS, announces the discovery of a new super-Earth orbiting a star slightly cooler than our Sun.

The Euclid mission delivers its first batch of data-valuable information to help unravel, among other things, the mystery of dark matter. The European Space Agency's (ESA) Euclid mission has unveiled its first public data, offering unprecedented insights into the structure and evolution of the Universe.

How do rogue planetary-mass objects - celestial bodies with masses between stars and planets - form? An international team of astronomers, including the University of Zurich, has used advanced simula

An international research team led by the University of Bern and Brown University in the US state of Rhode Island may have solved the mystery of the reddish color of Mars. The team identified the water-rich iron mineral ferrihydrite as the main culprit of the characteristic reddish Martian dust. This discovery could not only explain the planet's color, but also point to a wetter, potentially habitable Martian past.

An international team, including UNIGE, has reproduced for the first time the formation and evolution of a magnetar. Magnetars are a class of neutron stars with the strongest magnetic fields in the Universe. These incredibly dense objects are central in the landscape of extreme phenomena such as hypernovae, fast radio bursts, and gamma-ray bursts.

Researchers from the University of Bern, in collaboration with the University of Science and Technology Houari Boumediene in Algeria, have made significant progress in astrobiology. In a recently published study, they were able to detect fossil microorganisms in Messinian gypsum, which is found in Algeria, using the Bernese mass spectrometer LIMS.

Meteoroid impacts create seismic waves that cause Mars to shake stronger and deeper than previously thought: This is shown by an investigation using artificial intelligence carried out by an international research team led by the University of Bern. Similarities were found between numerous meteoroid impacts on the surface of Mars and marsquakes recorded by NASA's Mars lander InSight.

An international team, including the University of Geneva, has discovered a super-Earth that will enable astronomers to test new hypotheses in the search for life in the Universe. Thirty years after the discovery of the first exoplanet, we detected more than 7000 of them in our Galaxy. But there are still billions more to be discovered! At the same time, exoplanetologists have begun to take an interest in their characteristics, with the aim of finding life elsewhere in the Universe.

A UNIGE study shows that Hot Jupiters do not systematically eject their planetary neighbours during migration. This discovery overturns our perception of the architecture of planetary systems. Hot Jupiters are giant planets initially known to orbit alone close to their star. During their migration towards their star, these planets were thought to accrete or eject any other planets present.

For millennia humans have been inspired by the stars but this may soon be a thing of the past due to a significant increase in the numbers of satellites, potentially limiting our view of the night sky.

By analyzing a Martian meteorite, scientists from the University of Lausanne and Curtin University have discovered traces of water dating back 4.45 billion years in the crust of Mars, i.e. to the beginning of the Red Planet's formation. This new information reinforces the hypothesis that Mars may have been habitable at some point in its history.

An international team led by the University of Geneva has discovered three ultra-massive galaxies in the early Universe forming at unexpected speeds, challenging current models of galaxy formation. An international team led by the University of Geneva has identified three ultra-massive galaxies - nearly as massive as the Milky Way - already in place within the first billion years after the Big Bang.

"Magic" element challenges current model of nucleosynthesis Surprising measurements lead to the discovery of an unknown process.

A team of scientists including researchers from the University of Bern, the University of Geneva and the NCCR PlanetS used the ESPRESSO Spectrograph to discover a sub-Earth mass exoplanet orbiting Barnard's star, the second-closest star system to the Sun. This discovery helps to understand planetary formation around red dwarfs and provides insights into the diversity of planetary systems in our cosmic neighbourhood.

ETH spin-off Terensis is able to forecast the harvest yield and climate risks such as droughts and frost with the help of satellites.

An international team, including UNIGE, unveiled the "Neptunian Ridge", an overdensity of Neptunes nestled between the Neptunian Desert and the Neptunian Savanna. Astronomers have uncovered the ''Neptunian Ridge'', a newly identified feature in the distribution of exoplanets. This discovery, led by an international team including members of the University of Geneva, The NCCR PlanetS and the Centro de Astrobiología (CAB), highlights the complex dynamics within the Neptunian Desert, a region with a scarcity of hot Neptunes, and the Neptunian Savanna, where these planets are more commonly found.
