Astronomers Find ‘Impossible’ Galaxy ACDG-2 With Virtually No Stars and a Massive Dark Matter Core
Astronomers have identified CDG-2, a faint galaxy in the Perseus cluster that appears to be composed almost entirely of dark matter. Located 300 million light-years from Earth, it was discovered by tracking globular star clusters using data from Hubble, Euclid, and Subaru telescopes. Scientists estimate that about 99% of its total mass is dark matt...

Hubble Reveals How Blue Straggler Stars Stay Young in Ancient Clusters
Astronomers using the Hubble Space Telescope have uncovered new clues to the mystery of blue straggler stars—unusually hot, bright stars found in ancient globular clusters. By studying ultraviolet light from 48 clusters, scientists discovered that blue stragglers are more common in sparse clusters, supporting the idea that they form through binar...

NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems
Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

Hubble Uncovers Multi-Age Stars in Ancient Cluster, Reshaping Galaxy Origins
A stunning new image from NASA’s Hubble Space Telescope reveals that ancient star cluster NGC 1786—located 160,000 light-years away in the Large Magellanic Cloud—hosts stars of varying ages. Once believed to contain a single generation of stars, NGC 1786 now appears to preserve a more complex stellar history. This multi-age discovery suggests...

Hubble Observations Give Forgotten Globular Cluster Its Moment to Shine
NASA’s Hubble Space Telescope has unveiled ESO 591-12, a long-overlooked globular cluster glittering with multicolored stars. Captured during a survey of missing clusters, this image provides new insight into stellar evolution and the early Milky Way. It marks a vital step in resolving the structure and origin of ancient star systems hidden withi...

Researchers Spot Unusual, Overmassive Globular Clusters in Ultra-Diffuse Galaxy FCC 224
A new study has uncovered an unexpected globular cluster system in FCC 224, an ultra-diffuse galaxy located in the Fornax cluster. Using data from the Hubble Space Telescope and the Keck Cosmic Web Imager, researchers found that FCC 224 hosts luminous, overmassive globular clusters with unusual properties. The galaxy’s star clusters exhibit narro...

Research Reveals New Details About NGC 5018 Galaxy’s Clusters
A recent study of the NGC 5018 galaxy group, located about 132.5 million light years away in the Virgo constellation, provides new insights into its globular cluster (GC) system. Researchers analysed deep imaging data from the VLT Survey Telescope, revealing thousands of GC candidates, with a significant concentration around NGC 5018 itself. The st...

NASA Citizen Scientists Discover Mysterious Object Moving out of Milky Way at an Extremely High Speed
On August 15, 2024, NASA’s Backyard Worlds: Planet 9 project, featuring the contributions of dedicated citizen scientists, made a groundbreaking discovery: an object moving at an astonishing speed of 1 million miles per hour, which will soon escape the gravitational pull of the Milky Way. This hypervelocity object, catalogued as CWISE J124909.08+...
