First images from the James Webb telescope

Tuesday 12 July 2022
Rijksmuseum Boerhaave
Six months after launch, the James Webb telescope is ready to show its first color images. On Tuesday 12 July, these first images from the world's largest space telescope will be released by NASA, ESA and CSA during a live TV broadcast. At the Rijksmuseum Boerhaave we will be commemorating this historic moment together with world-famous Leiden astronomer Ewine van Dishoeck, who will be providing her insight on this scientific highlight. 

In collaboration with Ewine and her team, we are organizing an event around the release on Tuesday 12 July to show how important the James Webb telescope is. For us and Leiden this is extremely relevant, because Leiden scientists have made very important contributions to its development! 

Before we watch the live broadcast, Ewine will give an introductory lecture on the James Webb telescope and what we might expect from the images. After watching the broadcast, Ewine will comment on the images with fellow astronomer Bernhard Brandl. There will also be an opportunity to ask questions. Both the broadcast and the lecture will be in English.
