With a constellation of five satellites, the international LIFE initiative led by ETH Zurich hopes to one day detect traces of life on exoplanets. A laboratory experiment in the Department of Physics is now set to demonstrate the planned measurement method.

The JUICE mission of the European Space Agency ESA, which aims to explore the planet Jupiter and its three largest moons, is all set to go. The space probe will carry on board the high-tech detector RADEM developed at the Paul Scherrer Institute PSI. Among other things, this will provide information about the complex radiation conditions and the highly dynamic magnetic environment of the Jupiter system.

When it comes to measuring how fast the Universe is expanding, the result depends on which side of the Universe you start from. A recent EPFL study has calibrated the best cosmic yardsticks to unprecedented accuracy, shedding new light on what’s known as the Hubble tension.

For a long time it has been suspected that fullerene and its derivatives could form naturally in the universe. These are large carbon molecules shaped like a football, salad bowl or nanotube. An international team of researchers using the Swiss SLS synchrotron light source at PSI has shown how this reaction works. The results have just been published in the journal Nature Communications.

Around the world, the race is on to achieve a decisive breakthrough in quantum research. ETH Zurich is spearheading its own challenge.
