Astronomers look 3.5 billion years into the past

Using deep imaging data from JWST, two McMaster astronomers look 3.5 billion years into the past to study a remote giant cluster of galaxies. Marta Reina-Campos, a postdoctoral fellow and Canadian Institute for Theoretical Astrophysics National Fellow, and William Harris, an emeritus professor, collaborated in a new study to study a galaxy cluster called Pandora's Cluster.
