Using the San Pedro Martir Observatory and data from ESA's Gaia satellite, astronomers have inspected two old open clusters (OCs) known as NGC 1798 and NGC 1193. Results of the study, published July 13 on the arXiv pre-print ...
By analyzing the data from the Spektr-RG (SRG) space observatory and from the Zwicky Transient Facility (ZTF), astronomers from the California Institute of Technology (Caltech) and elsewhere have discovered two new polars. ...
By analyzing the data from ESA's Gaia satellite, Chinese astronomers have discovered 541 new open cluster candidates in the disk of our Milky Way galaxy. The finding, which includes median parameters of these cluster candidates, ...
European astronomers have observed a source on the sky known as Gaia20eae, which recently entered a phase of significant outbursting activity. Results of the new study suggest that this source may be an EXor-type eruptive ...
Scientists have spotted a previously unrecognized feature of our Milky Way galaxy: A contingent of young stars and star-forming gas clouds is sticking out of one of the Milky Way's spiral arms like a splinter poking out from ...

Using data from ESA's Gaia satellite, astronomers have investigated a low-metallicity galactic open cluster known as NGC 2158. The study, presented in a paper published December 11 on the arXiv pre-print server, provided ...
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 ...
