Astronomers have identified what could be the largest structure ever observed in the known universe—a vast network of galaxy clusters and superclusters containing an astonishing 200 quadrillion solar ...

The largest known structure in the Universe may be even larger than the large we thought it was. A re-examination of the distribution of powerful space explosions suggests that the Hercules-Corona ...

Astronomers have uncovered a vast, razor-thin strand of galaxies that is not just drifting through space but spinning ...

Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other ...

The formation of cosmic structure, on both large scales and small scales, is highly dependent on how dark matter and normal matter interact, as well as the initial density fluctuations that have their ...

The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like ...

As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow emptier. As ...

Every year, the Nobel Prize reminds all of humanity to appreciate all that we’ve achieved scientifically and to be aware of how that newfound knowledge has impacted us as a species. To a scientist, it ...

The FLAMINGO super simulation maps the universe from its earliest moments but finds galaxies cluster less than cosmological ...

FLAMINGO simulation maps the universe but reveals a puzzling mismatch: galaxies cluster less than theory predicts.

A team of researchers led by the University of Arizona recently used NASA’s James Webb Space Telescope (JWST) to examine a group of 10 galaxies that existed only 830 million years after the Big Bang, ...

The universe has no brain. It has no gray matter, no nervous system, no neurons firing electrical impulses—and yet, that ...
