Hidden star cluster discovered in Milky Way's crowded disk defies easy classification

Astronomers have discovered a stellar cluster hidden in the crowded disk of the Milky Way. The object, named Garro 04, was first identified as an unusual collection of stars in observations from the VVVX survey and was later confirmed using infrared spectroscopy. A paper outlining the properties of this seemingly mysterious stellar system was posted to the arXiv preprint server on September 21.
