DOI: 10.48550/arxiv.2604.11765 Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), astronomers have observed a nearby young open cluster known as NGC 1647. Results of the new observations, presented in a paper published April 13 on the pre-print server arXiv , deliver essential information regarding the properties of this cluster. Open clusters (OCs), formed from the same giant molecular cloud, are groups of stars loosely gravitationally bound to each other. So far, more than 1,000 of them have been discovered in the Milky Way, and scientists are still looking for more, hoping to find a variety of these stellar groupings. Studying OCs in detail could be crucial for improving our understanding of the formation and evolution of our galaxy.…
