Puzzle about nitrogen solved thanks to cometary analogues
One of the basic building blocks of life is nitrogen. An international consortium was able to detect ammonium salt containing nitrogen on the cometary surface of Chury thanks to a method using analogues for comet material. The method on which the study on the detection of ammonium salt is based was developed at the University of Bern.

Iron rain in the evening on a giant exoplanet
An international team of astronomers, led by UNIGE, has discovered a planet where it rains iron. Thanks to a new instrument conceived by the University of Geneva , Switzerland, and set at the Very Large Telescope (VLT) of the European Southern Observatory (ESO), an international team of researchers, led by UNIGE, has observed a planet featuring iron rains.

Solved: the mystery of the expansion of the universe
A researcher from the University of Geneva has solved a scientific controversy about the speed of the expansion of the universe by suggesting that it is not totally homogeneous on a large scale. The earth, solar system, entire Milky Way and the few thousand galaxies closest to us move in a vast "bubble" that is 250 million light years in diameter, where the average density of matter is half as large as for the rest of the universe.

Tracking down the mystery of matter
Researchers at the Paul Scherrer Institute PSI have measured a property of the neutron more precisely than ever before. In the process they found out that the elementary particle has a significantly smaller electric dipole moment than was previously assumed. With that, it has also become less likely that this dipole moment can help to explain the origin of all matter in the universe.

The seismicity of Mars
Fifteen months after the successful landing of the NASA InSight mission on Mars, first scientific analyses of ETH Zurich researchers and their partners reveal that the planet is seismically active. The recorded data enables a better understanding of the interior of Mars, the primary goal of the InSight mission.

CHEOPS space telescope takes its first pictures
Next milestone in the commissioning of CHEOPS: After the successful opening of the space telescope cover on January 29, 2020, CHEOPS has now taken its first images of the sky. CHEOPS is a joint mission of the European Space Agency (ESA) and Switzerland, led by the University of Bern, in collaboration with the University of Geneva.

The salt of the comet
Under the leadership of astrophysicist Kathrin Altwegg, Bernese researchers have found an explanation for why very little nitrogen could previously be accounted for in the nebulous covering of comets: the building block for life predominantly occurs in the form of ammonium salts, the occurrence of which could not previously be measured.

Interstellar journey of life’s building block phosphorus unveiled
Phosphorus, present in our DNA and cell membranes, is an essential element for life. But how it became available on the early Earth when life appeared here about 4 billion years ago is something of a mystery. For the first time, astronomers - among them researchers from the University of Bern - have now been able to show that molecules with phosphorus are formed in star-forming regions and probably came to Earth with comets.

Meteorite contains the oldest material on Earth
Researchers determined the age of stardust from a meteorite to be seven billion years - the oldest solid material ever found on Earth. Stars have life cycles. They're born when bits of dust and gas floating through space find each other and collapse in on each other and heat up. They burn for millions to billions of years, and then they die.

Cosmic magnifying glasses show faster expanding universe
New measurements using gravitational lensing, an innovative method that EPFL researchers have been working on for many years, suggest the universe is expanding faster than previously thought. A team of astronomers using NASA's Hubble Space Telescope have announced that the universe is expanding faster than expected.

A neural network as an anchor point
Quantum mechanics is a well-established theory, but at a macroscopic level it leads to intractable contradictions. Now ETH physicists are proposing to resolve the problem with the aid of neural networks. Necessity is the mother of invention.

CHEOPS launched successfully
Following the successful launch of CHEOPS, and once routine tests of the satellite in orbit have been completed, operations are set to begin at the end of March 2020 and last around four years.

Stardust from red giants
Some of the Earth's building material was stardust from red giants, researchers from ETH Zurich have established. They can also explain why the Earth contains more of this stardust than the asteroids or the planet Mars, which are farther from the sun. Around 4.5 million years ago, an interstellar molecular cloud collapsed.

This Nobel Prize makes EPFL's astrophysicists proud
In 2002, EPFL awarded the distinction of doctor honoris causa to Michel Mayor, an astronomer at the University of Geneva, for discovering the first exoplanet. This past Tuesday, Mayor, along with colleague Didier Quéloz and the American scientist James Peebles, was awarded the Nobel Prize in Physics.

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.

Nobel Prize in Physics awarded to Michel Mayor and Didier Queloz
Michel Mayor and Didier Queloz were awarded the 2019 Nobel Prize in Physics for their discovery of the first exoplanet in 1995. On October 6, 1995, Michel Mayor, Professor at the Observatory of the Faculty of Science of the University of Geneva (UNIGE), Switzerland, and the doctoral candidate Didier Queloz revolutionized the world of astrophysics when they announced the discovery of the first planet located outside our solar system.

A planet that should not exist
Astronomers detected a giant planet orbiting a small star. The planet has much more mass than theoretical models predict. While this surprising discovery was made by a Spanish-German team at an observatory in southern Spain, researchers at the University of Bern studied how the mysterious exoplanet might have formed.

Artificial intelligence probes dark matter in the universe
A team of physicists and computer scientists at ETH Zurich has developed a new approach to the problem of dark matter and dark energy in the universe. Using machine learning tools, they programmed computers to teach themselves how to extract the relevant information from maps of the universe. Understanding the how our universe came to be what it is today and what will be its final destiny is one of the biggest challenges in science.

The stellar nurseries of distant galaxies
An international team headed by UNIGE has discovered that the properties of molecular clouds, and the number of stars they produce, are different depending on whether they are in distant or nearby galaxies. Star clusters are formed by the condensation of molecular clouds, masses of cold, dense gas that are found in every galaxy.

Hints of a volcanically active exomoon
A rocky extrasolar moon (exomoon) with bubbling lava may orbit a planet 550 light-years away from us. This is suggested by an international team of researchers led by the University of Bern on the basis of theoretical predictions matching observations. The "exo-Io" would appear to be an extreme version of Jupiter's moon Io.
