Researchers say they've discovered the largest known object in the universe, a galactic superstructure called Quipu.

The Quipu superstructure is enormous, spanning 1.4 billion light years – and it could violate one of our fundamental ...

"This process is like a cosmic CT scan, where we can look through different slices of cosmic history and track how matter clumped together at different epochs." ...

The data, which was published ... paints a picture of the universe's infancy by using a distant, faint light that's been traveling since the Big Bang," says first author of the paper Joshua ...

The research suggests that the universe has become “messier and more complicated” over time, with a less clumpy distribution of matter.

The Einstein ring, formed as light from a distant galaxy bends to glow around another object in the foreground, could help ...

A unique dataset of Type Ia Supernovae being released today could change how cosmologists measure the expansion history of the Universe.

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.

This discrepancy between model and data became known as the ... explains it as trying to build the Universe's growth chart: we know what size it had at the Big Bang, but how did it get to the ...
