Enlarge / From left to right, zooming in from the globular cluster to the location of the black hole. ESA/Hubble & NASA, M. Häberle Supermassive black holes appear to reside at the center of every galaxy, and have done so since galaxies formed early in the history of the universe. However, we currently cannot fully … Read more
The Omega Centauri star cluster contains millions of stars. The motion of some of the stars suggests that there is a medium-sized black hole at its center. NASA/ESA/STScI/AURA hide caption switch caption NASA/ESA/STScI/AURA Astronomers using the Hubble Space Telescope have found evidence for the existence of an elusive type of black hole, about 8,000 times … Read more
The exposure-corrected image of SPT J2031. Credit: Diwanji et al., 2024. Using NASA’s Chandra X-ray spacecraft, astronomers from the University of Alabama in Huntsville have observed a merging cluster of galaxies known as SPT-CLJ 2031-4037. They discovered a rarely seen strong shock front in this cluster of galaxies. The finding was reported in a research … Read more
It’s a bird… it’s a plane… it’s a super star cluster! NASA’s Chandra X-ray telescope has imaged a star cluster that is “super” in every way. Westerlund 1 is super big, super massive, super young, super close – and it’s creating stars at a super fast pace. Westerlund 1 is about 13,000 light-years away from … Read more

Westerlund 1 is the largest and closest ‘super’ star cluster to Earth. New data from NASA’s Chandra These are the first data released publicly from a project called the Extended Westerlund 1 and 2 Open Clusters Survey, or EWOCS, led by astronomers at Italy’s National Institute of Astrophysics in Palermo. As part of EWOCS, Chandra … Read more
Strange behavior in a huge cluster of merging galaxies could be explained if dark matter, the universe’s most mysterious stuff, can collide with itself. However, the most favored model of cosmology at the moment is the Cold Dark Matter (CDM) model – and it suggests that dark matter, which is effectively invisible because it does … Read more
Using the Euclid Space Telescope, scientists have discovered a whopping 1.5 trillion orphan stars floating through a massive cluster of thousands of galaxies, one of the largest structures in the cosmos. These orphan stars, torn from their own galaxies, fill the space between the galaxies of the Perseus cluster with ghostly blue light. This so-called … Read more
