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 ...

Cosmologists are finally beginning to sketch a coherent picture of the universe we cannot see, using exquisitely detailed maps of galaxies, ghostly light and the large scale structure of space itself.

SEATTLE – An international team of astronomers using NASA’s Hubble Space Telescope has created the first three-dimensional map of the large-scale distribution of dark matter in the universe. Dark ...

A still image from the 3D animation created from data collected by the Keck Cosmic Web Imager (Caltech/R. Hurt) (CN) — Outer space may seem dark and impossibly vast, a mostly empty place punctuated ...

Caltech scientists have achieved a significant milestone in cosmic observation, using the Keck Cosmic Web Imager (KCWI) to directly capture light emitted by the cosmic web in the depths of space. This ...

Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web, are very faint and hard to see. While ...
