Galaxy clusters are formed by a dense packing of many galaxies, making them the most massive structures in the universe.

A newly discovered cluster-scale strong gravitational lens, with a rare alignment of seven background lensed galaxies, provides a unique opportunity to study cosmology. In a rare and extraordinary ...

ESA’s XMM-Newton X-ray observatory has revealed three massive filaments of hot gas flowing towards a cluster of galaxies, uncovering a portion of the cosmic skeleton that pervades the entire Universe.

NASA’s Hubble Space Telescope has photographed a massive galaxy cluster, appearing to show “contorted streaks and arcs of light” curved by the gravity of the mass. The warped arcs of light come from ...

Astronomers using NASA’s Hubble Space Telescope have spotted for the first time a distant supernova split into four images. The multiple images of the exploding star are caused by the powerful gravity ...

Astronomers used a cosmic lens to reveal a hyperactive protocluster. ALMA and VLA observations uncover tightly packed ...

In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a ...
