Space Telescope Data Opens a New Mapping Project

In this lesson: Connect a released collection with work that remains unfinished.

Name: __________________________ Date: __________________

Read the story

ESA released Euclid’s first major collection of mission data on November 12. The observations cover roughly 13 months and include more than a billion objects.

They provide material for a detailed three-dimensional map. The release lays a foundation for that work; it does not mean the entire map is finished.
