The James Webb Space Telescope: Canada's Crest

James Webb's Space Telescope banner

The Webb telescope will be the most complex and powerful telescope ever built. Located 1.5 million km from Earth, Webb will examine the first galaxies to form after the Big Bang, the formation of solar systems capable of supporting life on planets like Earth, and the evolution of our own Solar System.

This crest symbolizes Canada's two contributions to the Webb, which guarantees Canada's share of observing time. The target represents the Canadian Fine Guidance Sensor (FGS), which will keep the telescope precisely aimed. The Near-InfraRed Imager and Slitless Spectrograph (NIRISS), represented by the swirl, will offer unique science capabilities for finding the most distant objects, and discovering and characterizing planets in other solar systems.

The Webb telescope is a collaboration between NASA, the European Space Agency and the Canadian Space Agency. COM DEV built Canada's instruments, with a science and technical team led by the Université de Montréal.
