European astronomers have performed a comprehensive study of the young open cluster NGC 2345. The new research resulted in determining fundamental parameters of dozens of stars in the cluster and also unveiled the presence ...
Using data from ESA's Gaia satellite, German astronomers have detected a new open cluster in the Milky Way galaxy. The newly found cluster, designated Gaia 8, consists of about 100 stars, most likely including the Beta Lyrae ...
Astronomers have performed a comprehensive study of stellar populations in the young globular cluster NGC 1866. The new study confirms that the cluster hosts multiple stellar populations, which could have implications for ...
Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that chronological age alone does ...
