By analyzing the data from 2MASS and Gaia-EDR3 surveys, as well as images from NASA's WISE spacecraft, a Brazilian astronomer has inspected a galactic open cluster (OC) known as NGC 1605. The study, presented in a paper published ...
The Fornax Cluster—which, as the name suggests, lies primarily in the constellation Fornax (the Furnace)—is a relatively nearby galaxy cluster, only about 60 million light-years from Earth. This means that it looms large ...
