Euclid telescope: A scientist tells us of his quest to understand the nature of dark matter and dark energy

A traveller puts his head under the edge of the firmament in the original printing of the Flammarion wood engraving.On July 1st 2023, Euclid, a unique European space telescope was launched from Cape Canaveral. The launch was undoubtedly the highlight of my career as an astronomer, but witnessing the result of years of work being put on a rocket is not for the faint of heart. Following a perfect launch,. Over the past century we have made tremendous progress.

But how can we study the distribution of matter, if most of it is invisible dark matter? Fortunately, nature has provided a convenient way forward:around it. Clumps of dark matter reveal their presence by distorting the shapes of more distant galaxies, just like waves on the surface of a swimming pool distort the pattern of tiles on the bottom.Euclid image of the Perseus cluster of galaxies.

An illustration of strong lensing and how weak gravitational lensing distorts the observed shapes of a field of galaxies if matter is in the foreground near the line-of-sight : The presence of matter between the background galaxies and us causes a coherent distortion in their shape and orientation. If done for a large part of the sky, such a distortion measurement carries valuable information about the distribution of matter across cosmic time.
