All of a sudden, everyone is talking about it: the 2019 Nobel Prize won by Michel Mayor and Didier Queloz has reminded the Swiss that the country’s astrophysicists are at the forefront of the hunt for exoplanets, as they are in many areas of space exploration and research.

The 1995 discovery made little noise outside scientific circles. But as the years passed, the public began to realise that what was once the realm of science fiction had become a proven reality: the galaxy is teaming not only with stars, but also with planets. The first to have identified one of these planets orbiting a star other than our sun were none other than Switzerland’s own Michel Mayor and Didier Queloz.
24 years later, the discovery earned Mayor and Queloz the Nobel Prize for physics.
Excitement aside, the Nobel Prize is certainly justified. The discovery was one of the most important in astronomy in the 20th century. It opened new fields of research for understanding our place in the universe and it multiplied by millions the chances of finding extra-terrestrial life. For the 20th anniversary of the discovery of this first exoplanet, I wrote a detailed article on the subject.
But the search for other lifeforms is not an easy task when we are looking for it on distant worlds that are hundreds of thousands of billons of kilometres away. This is where human ingeniousness intervenes. And here also, is where the Swiss are present.
Ingenuity was required from the very outset of this quest. But how is it, in fact, that we are sure of the existence of these planets when, apart from on one or two grainy photographs of vague spots of light, no one has ever seen them? Video explanation.
Today it’s about going further. Understanding what exoplanets are made of is the mission of the CHEOPS spatial telescope, the first European satellite ‘Made in Switzerland’ that was launched last December.
But the Swiss reputation in space exploration was not established with CHEOPS, neither with Mayor and Queloz, nor even with the Swiss astronaut Claude Nicollier – first non-American mission specialist at NASA.
In 1969, Armstrong and Aldrin landed on the moon wearing Swiss watches on their wrists. And the first thing they did upon arrival, even before unfurling the star-spangled banner, was to install a solar sail from the University of Bern, itself being the only non-American scientific experiment on board Apollo 11.
Since the beginning of space exploration, there has hardly been an American or European mission which did not include Swiss technology. That’s because this country knows how to make instruments which are both very precise and very reliable, indispensable attributes for responding to the constraints of a space voyage.
Whether it is propelling a rover on Mars, ‘sniffing’ the gas which escapes from a comet or taking high definition images of a planet in the solar system, Swiss engineers have the solution.
The most recent example: STIX. This X-ray telescope will study solar eruptions from a European probe which will approach closer to the Sun than anything that has been attempted before.
Switzerland, country of watchmaking and precision mechanics also has highly advanced education and research support systems, which explains in part how a small country in the mountains has become a big country in space.
