Galaxies
The Large Magellanic Cloud is a companion galaxy to our own Milky Way and contains about 10 billion stars. At a distance of slightly less than 50 kiloparsecs (≈160,000 light-years) it is the third closest galaxy to our own. It is visible as a faint “cloud” in the night sky of the southern hemisphere straddling the border between the constellations of Dorado and Mensa. The first recorded mention of it was by the Persian astronomer, `Abd al-Rahman al-Sufi (later known in Europe as “Azophi”), in his Book of Fixed Stars around 964 AD.
