Cosmologists eventually decided that the expansion was being driven by a force they called dark energy and began to develop a ...

A new study published in the Journal of Cosmology and Astroparticle Physics (JCAP) presents a methodology to test the ...

Astronomers have discovered a cosmic superstructure so massive it reshapes our understanding of the universe's largest-scale ...

Early data of “little red dots,” or LRDs, from the James Webb Space Telescope (JWST) appeared to suggest the presence of galaxies too massive to exist in our modern cosmological models.

Black holes and soccer balls don't have much in common, but if black holes are curved when kicked, it might say something ...

With a length of 428 megaparsecs, or around 1.39 billion light-years, the superstructure is the biggest ever spotted.

Scientists have come up with a number of possible explanations. One of the leading concepts is the ‘cosmological constant’ theory, in which the energy of empty space itself causes cosmic acceleration.
