Myriads of unknown and really distant galaxies, a huge cluster of stars captured at a look as has by no means occurred earlier than, cradles of planets seen by penetrating the curtain of mud that hides them: they’re snapshots of the universe as nobody has ever seen it, the primary 5 scientific photographs from the Euclid house telescope, introduced by the European House Company and already thought of revolutionary. They’re nonetheless a check, however they comprise traces of the darkish matter and vitality that occupy 95% of the cosmos and that Euclid must assist us perceive. Italy is collaborating in an necessary method on this 1.4 billion euro mission.
For consultants, the revolutionary significance of those first photographs is already clear.
The primary is that of the Perseus cluster: along with the thousand galaxies within the cluster, the picture exhibits one other 100,000 far more distant ones, some very faint and by no means seen and others so distant that their mild has traveled for 10 billion years earlier than of being captured by Euclid’s instruments.
One other picture is that of the spiral galaxy IC 342, generally known as the ‘Hidden Galaxy’, which Euclid was capable of reveal due to its infrared imaginative and prescient. Then there may be the galaxy NGC 6822, whose irregular form reveals its primitive nature and there may be the globular cluster NGC 6397, of which Euclid captured all of the lots of of hundreds of stars directly. Lastly, the telescope managed to penetrate past the gasoline and dirt that encompass the Horsehead Nebula, discovering planets in formation and new child stars.
They’re lovely shade photographs of the seen universe. They subsequently correspond to five% of the universe, however they’re step one in direction of figuring out the darkish facet which occupies 95% of it, made up of the invisible matter which occupies 25% of it and the driving vitality of its growth which occupies it for 70% and up to now fully unknown.
Launched on July 1, 2023, the Euclid telescope obtained the primary check photographs on July 31 and these first scientific photographs are a primary demonstration of how a lot this instrument is able to doing. Precise knowledge assortment is anticipated to begin in January 2024. Designed to function for six years, Euclid is meant to acquire probably the most intensive 3D map of the universe.
The mission is a superb staff effort involving 20 European international locations, plus the US with NASA, 300 analysis institutes and 80 corporations, for a complete of three,500 energetic folks and 140 industrial contracts. Beneath the steerage of the Italian House Company, Italy collaborates with the Nationwide Institute of Astrophysics, the Nationwide Institute of Nuclear Physics and the Nationwide Heart for Analysis in Excessive Efficiency Computing, Large Information and Quantum Computing, which makes computing assets accessible for analysis and personnel for the simulation and theoretical modeling actions crucial for the scientific evaluation of the information that can assist construct the 3D map of the universe. Quite a few Italian universities additionally take part, together with these of Bologna, Ferrara, Turin, Genoa, Salento and Trieste, Statale di Milano, Sapienza di Roma, Roma Tre, Sissa and Cisas. ASI, with Inaf and Infn, additionally leads the momentary enterprise affiliation that contributed to the instruments, with Ohb Italia as agent, Sab Aerospace and Temis as principals.
