This image of Caldwell 69 combines ultraviolet, visible, and infrared observations captured by Hubble's Wide Field Camera 3 during 2019 and 2020. NGC 6355 is a globular cluster positioned in the inner ...

And what they discovered changes our understanding of these structures. Gran 5 is not a cluster like the others. Located about 14,600 light-years away, it is composed of stars with distinct chemical ...

Most stars form in collections, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively ...

Our best view yet of the material linking clusters of galaxies may have pinpointed some 20 percent of the universe’s missing ...

The cluster contains hundreds of massive ... NASA's now-retired Spitzer Space Telescope (red, green, blue, and cyan) reveals young stars and the cooler dust and gas throughout the region.

The results of our study provide the first solid evidence that globular clusters formed through multiple star-formation events and place fundamental constraints on the dynamical path followed by ...

NASA’s Hubble Telescope captures stunning images of galaxies merging in the Coma Cluster, offering a glimpse into galactic ...

In addition, it was found that at least 64% of the 14 known blue straggler stars (BSS) of NGC 2506 are in binary systems. More information: Evan Linck et al, WIYN Open Cluster Study. XC.

The Hubble Space Telescope has captured a spiral galaxy under the "ram pressure" inside a massive cluster of galaxies.

The new research has provided astronomers with the most detailed description of how stars move within globular clusters, and the clusters' overall evolution from their formation to the present day.
