Its story

In the Crane — that southern bird introduced by Dutch navigators returning from the East Indies — this F-type yellow-white star shines from 116 light-years away. It runs hotter than the Sun and, at this relatively close range, is one of the most easily measured stars in the constellation. Its light carries the cool tinge that separates, on a truly dark night, the young incandescents from the swollen reddened giants.
