Remapping the skies

In the 1660s, the famous Polish astronomer Johannes Hevelius set out to create more accurate charts by remapping the skies. He used his naked eye and a very large sextant to make new observations, discovering many additional stars. He also consulted and studied observations made by earlier scholars from Muslim civilisation.

Hevelius published in 1687 a comprehensive atlas of the constellations on the basis of his observations and additional resources. At his request, the Royal Society in London translated into Latin a renowned star catalogue produced in 1487 by the astronomer-mathematician Ulugh Beg, which he studied along with observations made in the 10th century by Persian astronomer Al-Sufi in his book 'Forms of Fixed Stars'.
