Two massive galaxies are bending light from the same distant quasar, creating a so-called Einstein zigzag lens that could help astronomers pin down how quickly the universe is expanding ...

New observations suggest that the universe’s oldest galaxies are brighter than expected. Here's why this may be a big deal.

who tend to favor cold dark matter theories, because it has yet to explain a wide range of cosmological phenomena. On the other hand, dark matter theories can explain a lot of observations ...

"From current cosmological theories we didn't think structures on this scale were possible," Lopez said. "We could expect maybe one exceedingly large structure in all our observable Universe.

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...
