When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

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.

NASA's Chandra X-ray Observatory has discovered a surprisingly mature galaxy protocluster from the infancy of the universe. Galaxy clusters are among the largest-scale structures in the universe.

One of the hallmarks of the midwinter Colorado sky is the presence of a comparatively large number of stellar groupings, which are called “open” or galactic star clusters. Unlike the globular clusters ...

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 ...

An inexplicably hot, fast-growing cluster of galaxies in the early universe has scientists questioning theories of galactic evolution. When you purchase through links on our site, we may earn an ...
