Webb reveals a galaxy sparkling with the universe’s oldest star clusters

Using the James Webb Space Telescope (JWST), researchers from the CAnadian NIRISS Unbiased Cluster Survey (CANUCS) team, including York University, have identified the most distant globular clusters ever discovered. These dense groups of millions of stars may be relics that contain the first and oldest stars in the universe.

TORONTO, Dec. XX, 2021 – The new James Webb Space Telescope (JWST) – a collaboration between NASA, the European Space Agency and the Canadian Space Agency – is expected to launch this month with the Canadian-built Near-Infrared Imager and Slitless Spectrograph (NIRISS). It will take images and spectra of fainter objects than the Hubble Telescope ever could, and it’s creating an astronomical amount of excitement.
