Featured paperThe Local Star Formation Environment Predicts Young Star Cluster Radii: Evidence from PHANGS-MUSE H-alpha Maps

Young stars can live together in groups. Scientists looked at 325 young groups in four galaxies. Groups in busy star-making neighborhoods tended to be a little bigger, even when the scientists compared groups with similar masses and ages. Looking at a whole galaxy did not help in the same way. The nearby neighborhood may matter, but it does not explain all the size differences.
