From its perch 1 million miles (1.6 million kilometers) from Earth, Euclid will spend the next several years observing billions of galaxies covering more than one-third of the sky. The shape and size of all these galaxies can help scientists understand the mysterious dark energy and dark matter that make up most of the universe.
"Euclid is at the very beginning of its exciting journey to map the structure of the universe," the space agency's director general, Josef Aschbacher, said in a statement.
Among the newly released pictures is one of an enormous cradle of baby stars some 1,300 light-years away known as Messier 78. A light-year is 5.8 trillion miles. Euclid's infrared camera peered through the dust enveloping the stellar nursery, revealing new regions of star formation, according to ESA.
