The James Webb Space Telescope will find the first galaxies that formed in the early universe and peer through dusty clouds to see stars forming planetary systems.

NASA launch now planned for December 18, 2021

Map and list of official NASA supported locations hosting Webb community events

The map and list of selected NASA Webb Space Telescope community events is now available. You can still host an event if you aren't an "official" NASA Webb community event! Applications for a "NASA-supported Webb Space Telescope Community Event" closed May 16, 2021, but there are still many resources available for hosting an event.
