Using ESA's Gaia satellite, astronomers have serendipitously discovered a new open cluster in the Milky Way galaxy. The newfound cluster, which received the designation Ash-1, is relatively young ...

However, statistical methods allow for inferences about a population by analyzing the results of a smaller sample extracted from that population. Stratified random sampling is one way of doing this.

"Clusters rich in red supergiants are very rare and tend to be very far away, but they play a crucial role in understanding key aspects in the evolution of massive stars." In the past, map makers ...
