New observations from NASA's Chandra X-ray Observatory and other telescopes have captured a rare cosmic event: Two galaxy ...

Abell S1063 is so massive that the light from distant galaxies bends around it, allowing it to act as a magnifying glass to ...

A new investigation of the structure of galaxy clusters has found it agrees with ... The data they collected conform to a model of universal evolution and structure called the lambda cold dark ...

The galaxy’s sweeping spiral arms are filled with young blue star clusters and ionized hydrogen gas, indicating rapid star formation. Astronomers believe its bar-like structure channels gas ...

NGC 685, a smaller cousin of our Milky Way, dazzles with youthful energy as newborn stars light up its spiral arms.

The early universe was a stressful place for galaxies. Globs of tens to hundreds of neighboring galaxies, called galaxy clusters, would share a communal pool of hot gas—but not without drama.

In fact, galaxies don’t just exist alone, but often interact with each other — and often come together in vast groups called galaxy clusters. This week’s image from the Hubble Space ...

Each coloured circle depicts a galaxy group or cluster. The richest galaxy clusters are marked in red; these are the richest galaxy clusters in the Hercules and Leo superclusters. The side panels ...

It was discovered that these dots were five young massive star clusters. Through analysis of the light spectra emitted by the galaxy, it could be determined that the stellar clusters are ...

If you buy through a BGR link, we may earn an affiliate commission, helping support our expert product labs. Astronomers observing a mysterious radio halo from the galaxy cluster Abell 1213 have ...

What can heat distribution within galaxy clusters, which often consist of hundreds to thousands of galaxies, teach astronomers about their formation and evolution? This is what a recent study ...
