Euclid, the European mission to discover the unknown and darkish universe, took off Saturday aboard a SpaceX Falcon 9 rocket from Cape Canaveral, Florida.
The launch passed off at 15:12 GMT, and after separating from the rocket, Euclid will set a course for the purpose generally known as Lagrange 2, 1.5 million km from Earth – the place telescopes resembling Gaia and James Webb are -.
From there, for six years, he’ll observe billions of galaxies at a distance of as much as 10,000 million light-years, in additional than a 3rd of the sky; The aim is to create the biggest and most correct 3D catalog of the universe to attempt to advance data of the character of matter and darkish vitality.
It has by no means been noticed so far as it’s going to do that job, so one risk is that the cosmological commonplace mannequin works, however various equations may be a greater match.
Euclid was designed, at a value of 1,400 million euros (about $1,529 million at present alternate charges) and with the participation of Spanish corporations and analysis facilities, to supply new information on the unknown and darkish aspect of the universe.
With this 3D map of the universe (time is the third dimension), info can be collected on the shapes, places and distances of galaxies and can advance data of darkish matter and vitality, the way it has modified the growth of the universe or in understanding gravity.
Odd matter is that which contains planets, galaxies or stars and accounts for five%; The remaining is within the type of darkish vitality (about 70% of the universe) and darkish matter (25%), numerous elements that cosmology continues to be attempting to clarify.
