Today, the Euclid space telescope released its first major data set, capturing over a billion objects to map the dark universe.
The data, designated DR1-Foundation, was gathered over 13 months and includes spectra from 160 million sources, over 900 million galaxies, and 60 million quasar candidates.
Operating above Earth's atmosphere, the telescope can survey a vast area of sky without atmospheric interference, and the current release covers about 14% of its six-year survey goal.
Researchers anticipate that the dataset will enable detailed mapping of the large-scale structure of the cosmos and provide insights into dark energy and dark matter.
