Rare-Earth metals in the atmosphere of a glowing-hot exoplanet
KELT-9 b is the hottest exoplanet known to date. In the summer of 2018, a joint team of astronomers from the universities of Bern and Geneva found signatures of gaseous iron and titanium in its atmosphere. Now these researchers have also been able to detect traces of vaporized sodium, magnesium, chromium, and the rare-Earth metals scandium and yttrium.

Researchers Observe Slowest Atom Decay Ever Measured
Researchers Observe Slowest Atom Decay Ever Measured
The XENON1T detector is mainly used to detect dark matter particles deep underground. But a research team led by Zurich physicists, among others, has now managed to observe an extremely rare process using the detector - the decay of the Xenon-124 atom, which has an enormously long half-life of 1.8 x 10^22 years.

Five planets revealed after 20 years of observation
Five planets revealed after 20 years of observation
A team of astronomers led by the UNIGE has discovered five new planets with periods of revolution between 15 and 40 years. It took 20 years of regular observations to achieve this result. Over 4000 exoplanets have been discovered since the first one in 1995, but the vast majority of them orbit their stars with relatively short periods of revolution.

First image of a black hole
First image of a black hole
The Event Horizon Telescope (EHT) - a planet-scale array of eight ground-based radio telescopes forged through international collaboration - was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.

Neural networks predict planet mass
To find out how planets form astrophysicists run complicated and time consuming computer calculations. Members of the NCCR PlanetS at the University of Bern have now developed a totally novel approach to speed up this process dramatically. They use deep learning based on artificial neural networks, a method that is well known in image recognition.

"Better to dry a rocky planet before use"
Earth's solid surface and clement climate may be in part due to a massive star in the birth environment of the Sun. Without its radioactive elements injected into the early solar system, our home planet could be a hostile ocean world covered in global ice sheets. This is demonstrated by computer simulations in which the National Centre of Competence in Research PlanetS, based at the University of Bern, was involved.

Measurement of five flashes from the depths of the universe
Measurement of five flashes from the depths of the universe
First-time precise measurement of gamma-ray bursts conducted successfully from a space station A detector called POLAR, developed at PSI, has been sent to outer space to collect data. In September 2016, the device was launched into Earth orbit on board the newest Chinese space station. From that vantage point, POLAR recorded so-called gamma-ray bursts flashing in the far reaches of the universe.
