Galaxies are not islands in the cosmos. While globally the universe expands—driven by the mysterious "dark energy"—locally, ...

Using the VLT Survey Telescope (VST), astronomers from Italy and Germany have observed a group of galaxies designated NGC ...

Because the density of galaxies is high within clusters, galaxy collisions occur ... are attempting to measure millions of galaxies and map their distribution in space. We are only beginning ...

We have endeavored to create here a 3-D visualization of the distribution of nearby galaxies and galaxy clusters. It is a 3-D map, if you will, of the local universe, with the structures ...

A phenomenon called gravitational lensing turned a galaxy into a "hall of mirrors of cosmic proportions," allowing for the discovery.

Galaxy clusters contain up to thousands of galaxies ... constrain its integrated spectrum, and map the spectral index distribution," the researchers wrote in the paper. The new VLA observations ...

Study reveals NGC 5018's significant globular cluster population Radial density profile of globular clusters shows evolutionary patterns Tidal forces shape NGC 5018 galaxy group’s globular cluster sys ...

It’s almost globular cluster season. One of the mysteries of our galaxy and every other, these dense groupings of up to a million stars—the most massive and oldest star clusters in the ...

An international team of astronomers has discovered exciting new details about a nearby galaxy cluster merger, that provides a deeper understanding of galactic collisions. Using the Very Large ...
