Variable starIts story
4 Cygni is a hot, variable B-type blue star burning at 708 light-years inside the Northern Cross. Its brightness shifts slightly, a stellar breathing only fine instruments can detect. The light arriving tonight set out when Persian astronomers were still teaching Europe how to measure the sky, and it crossed the entire modern era without straying.
