Comet Chury’s ultraviolet aurora
On Earth, auroras, also called northern lights, have always fascinated people. An international consortium involving the University of Bern has now discovered such auroras in the ultraviolet wavelength range at comet 67P/Churyumov-Gerasimenko, Chury for short. This phenomenon was detected thanks to the analysis of data from the European Space Agency ESA's Rosetta mission.

Surprise on Mars
NASA's InSight mission provides data from the surface of Mars. Its seismometer, equipped with electronics built at ETH Zurich, not only records marsquakes, but unexpectedly reacts to solar eclipses as well. When the Martian moon, Phobos moves directly in front of the sun, the instrument tips slightly to one side.

Space debris observed for the first time during the day
Researchers at the University of Bern are the first in the world to succeed in determining the distance to a space debris object using a geodetic laser in daylight. The distance was determined on June 24, 2020 at the Swiss Optical Ground Station and Geodynamics Observatory Zimmerwald. The number of measurements can be multiplied thanks to the new possibility of observing space debris during the day.

The discovery of the first galaxy emitting "extreme" ultraviolet radiation could help to better understand how the cosmic era known as the "Dark Ages" came to an end more than 13 billion years ago. Thanks to the Indian satellite AstroSat, an international team, including astronomers from the University of Geneva, has detected the first galaxy, called AUDFs01, emitting "extreme" ultraviolet radiation, i.e. highly energetic (with a wavelength of about 60 nanometres, or billionths of a metre).

New instrument for the search for life in space
Researchers at the University of Bern have developed the highly sensitive instrument ORIGIN for future space missions, which can detect minute traces of life. Space agencies such as NASA have already expressed interest in testing ORIGIN for future missions. For example, the instrument could be used for missions to the icy moons Europa (Jupiter) and Enceladus (Saturn).

New tool helps interpret future searches for life on exoplanets
One way to determine whether there is life on another planet is to look for biosignatures in the light that is scattered off its atmosphere. Scientists at EPFL and University of Rome Tor Vergata have developed an original model that interprets the results of that analysis. Is there life on a distant planet? One way astronomers are trying to find out is by analyzing the light that is scattered off a planet's atmosphere.

A dead star emits a unique mixture of radiations
An international collaboration between ground-based and orbiting telescopes is shedding light on one of the mysteries of the universe. The alert was issued by ESA's Integral Space Observatory, whose scientific data are processed at the University of Geneva. An international network of telescopes, of which Integral, the high-energy space observatory of ESA (European Space Agency), is a part, has detected a unique mixture of radiation from a dead star in our galaxy.

First exposed planetary core discovered
Researchers led by the University of Warwick have discovered the first exposed core of an exoplanet, which provides an unprecedented glimpse inside the interior of a planet. Christoph Mordasini from the University of Bern is leading the theoretical interpretation of this discovery. The newly discovered exoplanet TOI 849 b offers the unique opportunity to peer inside the interior of a planet and learn about its composition.

Surprising Signal in Dark Matter Detector
When analyzing data from the XENON1T detector for dark matter, a signal excess was observed. The UZH researchers do not yet know for sure where this unexpected signal comes from. They say the origins could be relatively banal, but they could also indicate the existence of new particles or hitherto unknown properties of neutrinos.

First global map of rockfalls on the Moon
A research team from ETH Zurich and the Max Planck Institute for Solar System Research in Göttingen counted over 136,000 rockfalls on the moon caused by asteroid impacts. Even billions of years old landscapes are still changing. In October 2015, a spectacular rockfall occurred in the Swiss Alps: in the late morning hours, a large, snow-covered block with a volume of more than 1500 cubic meters suddenly detached from the summit of Mel de la Niva.

Confirmation of Earth-sized planet around the nearest star
The existence of an Earth-sized planet around the nearest star in the solar system, Proxima Centauri, has been confirmed by an international team of scientists including researchers from the University of Geneva. The results, published in the journal Astronomy & Astrophysics, reveal that the planet in question, Proxima b, has a mass of 1.17 Earth masses and is located in the habitable zone of its star, which it circles in 11.2 days.

A major step towards the explanation of the matter-antimatter asymmetry
The international T2K Collaboration has published results showing the strongest evidence to date implying the breaking of the symmetry between matter and antimatter in so-called neutrino oscillations. This is a major step towards the understanding of the dominance of matter over antimatter in the Universe.

CHEOPS space telescope ready for scientific operation
The CHEOPS space telescope has exceeded scientists' expectations for accuracy. CHEOPS has reached its next milestone: Following extensive tests in Earth's orbit, some of which the mission team was forced to carry out from home due to the coronavirus crisis, the space telescope has been declared ready for science.

Astronomy: six planets (almost) in rythm
An international team lead by researchers of the University of Geneva has discovered a six-planets system. Almost visible to the naked eye in the Draco constellation, the star HD 158259 has been observed for the last seven years by astronomers using the SOPHIE spectrograph. This instrument, installed at the Haute-Provence Observatory in the South of France, acquired three hundred measurements of the star.

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.

CO2 tracking in space
CO2 concentrations in the air continue to rise rapidly, and a rapid reduction in man-made emissions is becoming increasingly important. In order to assess the effectiveness of political measures, timely and reliable emission levels are needed. However, current methods are costly. The European Space Agency ESA is therefore working on the development of new satellites which will be able to determine CO2 emissions in the future - with the help of Empa.

Astrophysicists fill gaps in the history of the Universe
An international consortium of scientists has analyzed, as part of a vast program of cosmological surveys, several million galaxies and quasars, thus retracing a more continuous history of the Universe and offering a better understanding of the mechanisms of its expansion. The latest 6 year-long survey called eBOSS was initiated, and led in part, by EPFL astrophysicist Jean-Paul Kneib.
