Astronomers have performed spectroscopic observations of a globular cluster (GC) known as Djorgovski 2 and obtained chemical abundances of the cluster's seven stars. The results suggest that Djorgovski 2 contains multiple ...
"Clusters form big families of stars that can stay together for large parts of their lifetime. Today, we know of roughly a few thousand star clusters in the Milky Way, but we only recognize them because of their prominent ...

Once a black hole forms, its intense gravitational field produces a surface beyond which even light cannot escape, and it appears black to outsiders. All the details of the complex mix of matter and energy in its past are ...

Astronomers from India have conducted a long-term photometric variability survey of an open cluster known as NGC 559. As a result, they detected 70 new variable stars in the field of this cluster. The finding is presented ...
Chinese astronomers have conducted a study of variable stars in the galactic open cluster NGC 1912 and its surrounding field, detecting 11 new variables in this cluster, including binary systems. The study was detailed in ...
Astronomers have found that the key to understanding galaxies with "extreme" sizes, either small or large, may lie in their surroundings. In two related studies, an international team found that galaxies that are either "ultra-compact" ...

Using data from ESA's Gaia satellite, astronomers from the National Research Institute of Astronomy and Geophysics in Cairo, Egypt, have explored the open star cluster Kronberger 60. Results of the study, published September ...
Observations of magnetic fields in interstellar clouds made of gas and dust indicate that these clouds are strongly magnetized, and that magnetic fields influence the formation of stars within them. A key observation is that ...
