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 ...

MAUNA KEA, Hawaii (KHON2) — It has been described like rivers feeding oceans. The universe has streams of gas that nourish galaxies throughout the cosmos. But scientists said that these streams, which ...

The idea that gravity shapes the universe into nicely bounded superclusters is being overturned by a finding so gargantuan that it could send cosmologists back to the drawing board. The new mapping of ...

For decades, scientists have worked to map the universe’s large-scale structure, testing cosmological models and ...

Astronomers have reconstructed nearly nine billion years of cosmic evolution by tracing the X-ray glow of distant clusters of galaxies. The analysis supports the standard model of cosmology, according ...

An astronomer from the University of Hawaii Institute for Astronomy and an international team published a new study that reveals more of the vast cosmic structure surrounding our Milky Way galaxy. The ...

The interactive online map, created using data from NASA's James Webb Space Telescope, details some 800,000 galaxies across a vast cosmic distance. Scrolling and zooming in can take users some 13.5 ...
