Unlike previous missions that relied on small samples, Euclid provides massive statistical data, capturing high-resolution images of millions of galaxies.

nounEuclid

This enables scientists to track how galaxies transform from active, star-forming systems into massive elliptical structures.

Correct Choice

The 'building blocks' used to understand how larger galaxies formed.

How does Euclid differ from previous astronomy missions?

Correct Choice

It provides massive statistical data rather than focusing on small samples.
