Hot blue starWhat is HIP 90804
1,077 light-years away burns this hot-blue in Scutum, the baroque shield Hevelius drew in honour of a Polish king. Her blue-white light departed deep in the 10th century: the first Christian millennium still reigned and the Vikings ploughed the North Atlantic. B stars like this burn so quickly that by the time a human decodes their light, the star has already changed.
