"In order to collate all this data, we need long-term collaboration between observatories and data centers around the world, but once it is finished, it will also offer scientists the best material for research into the structure of the universe," says University Lecturer Aku Venhola from the University of Oulu. In addition to the data gathered by the space telescope, we also need a huge amount of data collected from Earth in order to determine the distances of galaxies. The Finnish members also hold a strong position in combining observations made from Earth with Euclid data. The Finnish scientists have collaborated in developing computing methods, producing simulated data, and developing data quality-assurance methods for Euclid. The observational data from Euclid will be analyzed in nine separate Euclid science data centers, one of which is located in Finland. The total cost of the project is more than 1 billion euros. More than 300 research institutes and 2,000 researchers from 21 countries are participating in Euclid. Euclid differs from previous space telescopes specifically in that it can take in a much larger portion of space at one time-the portion of space covered by one image is larger than the full moon can conceal. The images from visible light contain more than 600 million pixels and the ones from infrared more than 60 million pixels.Įuclid will take images from one area for over an hour, and then it will be turned towards another area. There is a telescope on Euclid with a diameter of 1.2 meters, along with two instruments: one for taking sharp images in visual light, the other one for taking spectra and images in infrared.īoth instruments on Euclid contain a large camera. This, in turn, depends on the characteristics of dark matter and dark energy.Įuclid will be launched from Cape Canaveral in Florida with a SpaceX Falcon 9 rocket to 1.5 million kilometers from Earth, where it will be able to make observations without interference. The three-dimensional map produced by Euclid will help us study how the universe has expanded and how large-scale structures, like galaxies, have developed during cosmic history. In this way we will be able to map the distribution of dark matter. Euclid will also measure the gravitational lens effect how the gravitation of dark matter bends the trajectory of light so that it distorts how we see far-away galaxies. The part of space to be mapped has been selected because that is where the furthermost galaxies are most clearly discernible, avoiding the plane of the Milky Way and our own solar system. The further away an observed galaxy is, the further we can see into the past-all the way to 10 billion years ago. The map will cover over one third of space, up to 10 billion light years away. Though we cannot see either of them directly, they make up some 95% of the universe," says Professor Hannu Kurki-Suonio from the University of Helsinki.Įuclid will produce a three-dimensional map of the universe with billions of galaxies. "The gravity of dark matter and dark energy affects the movements of galaxies and the expansion of the universe. The objective of Euclid is to help us understand two of the most enigmatic, yet key phenomena in the universe dark matter and dark energy. The main objective is to solve the problem of dark energy, i.e., why has the expansion of the universe started to accelerate?Ī map to reveal the secrets of dark matter and dark energy In six years, Euclid will complete a task that would take older telescopes like Hubble or Webb over a century.
