The so-called "dark universe," as its nickname indicates, is that region of the universe which is so distant from Earth that it is extremely difficult to observe. However — thanks to the European Space Agency's new powerful telescope, Euclid — the dark universe is now a little less dark than it was before. Indeed, thanks to Euclid's very first test images ever sent back to Earth, humanity can now see the dark universe not as a mysterious void, but as a place brimming with stars and other celestial objects.
Specifically the images revealed hundreds and hundreds of glittering stars, cosmic rays and a series of fuzzy blobs that the Euclid's operators explain are galaxies. The European Space Agency (ESA) plans on investigating those galaxies as part of its larger plan to create a detailed map of the universe.
