APOD: 2026 June 3 Б Andromeda Through Gas and Dust
3.06.2026

Over 1000 years ago, Persian astronomer Abd al-Rahman al-Sufi published humanityБs oldest known record of the Andromeda Galaxy in "The Book of Fixed Stars" (Bodleian Library MS. Marsh 144 p. 167). 800 years later, Andromeda became the 31st entry in Charles MessierБs "Catalogue of Nebulae and Star Clusters".
