How do galaxies form? Thanks to major technological advances, astronomers are gaining ever-deeper insights, says astrophysicist Mariska Kriek in her inaugural lecture. ‘It’s almost unbelievable how many significant discoveries the James Webb Space Telescope has already yielded in such a short time.…

The first full-colour images of the cosmos from ESA's space telescope Euclid were presented today. Never before has a telescope been able to take such crystal-clear astronomical images of such a large part of the sky and so far into the deep universe. The five images illustrate Euclid's full potential;…

Space telescope Euclid is capable of unravelling the secrets of the universe. That is what the images published by ESA today show, according to astronomers working with the telescope's data. The images exceed all expectations. Scientists within the Euclid consortium, including astronomers Henk Hoekstra…
