[The "Euclidean" space telescope released the first batch of important observation data, totaling 1.7 million GB] On November 13, according to the European Space Agency, the "Euclidean" space telescope released the first batch of important observation data on the 12th. The data includes captured light from more than 1 billion cosmic objects, covering an area of ​​sky equivalent to 9,500 full moons. This batch of data contains more than a year of observations and will help scientists draw the largest three-dimensional map of the universe to date, providing important basis for exploring dark matter, dark energy and other mysteries of the universe. This batch of data named "DR1-Foundation" is the first large-scale observation result released by the "Euclidean" telescope since its launch in 2023. It contains about 13 months of observation data and a total volume of 1.7 million GB. The data covers 1,900 square degrees of the sky, including more than 900 million galaxies, about 15,000 strong gravitational lens candidates, more than 60 million quasar candidates, and spectral information of more than 160 million objects.
