JWST observations of galaxy cluster MACS J1149 show gravitational lensing used by CANUCS to study distant low-mass galaxies across a wide range of cosmic time.

This NASA/ESA/CSA James Webb Space Telescope Picture of the Month brings us a scene from the distant universe. Pictured here ...

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of ...

The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to ...

Star clusters are collections of thousands to millions of stars bound together by gravity — and many can be observed in the night sky with binoculars or a small telescope. One notable example is ω ...

For years, scientists have worked to chart the universe’s massive structure, aiming to test key models of cosmology. These efforts also help uncover how galaxies form and change over time. While most ...
