Explanation: <\/b>
\nOver 1000 years ago, Persian astronomer
\nAbd al-Rahman al-Sufi<\/a>
\npublished humanity\u2019s oldest known record of
\nthe Andromeda Galaxy<\/a>
\nin “The Book of Fixed Stars”
\n(Bodleian Library MS. Marsh 144 p. 167<\/a>).
\n800 years later, Andromeda became
\nthe 31st entry<\/a>
\nin Charles Messier\u2019s
\n“Catalogue of Nebulae and Star Clusters<\/a>“.
\nFrom \u201ca small cloud\u201d to \u201cnebula\u201d and now known to be
\nour nearest major galaxy<\/a>,
\nAndromeda has remained a fundamental astronomical object.
\nToday\u2019s image<\/a>,
\ntaken over 202 hours, shows how far we have come in our ability to observe our neighbor.
\nThe diffuse red and blue clouds<\/a>
\nare mostly foreground ionized hydrogen and oxygen well within our
\nMilky Way<\/a>.
\nPink-red clouds of hydrogen
\nionized<\/a>
\nby the energetic light of young stars trace the galaxy\u2019s
\ndusty spiral arms<\/a>.
\nM32<\/a> and
\nM110<\/a>
\nare
\nsatellite galaxies<\/a>
\npictured orbiting the larger Andromeda. Despite its long history of observation through ancient unaided eyes to modern telescopes, Andromeda still holds countless secrets that
\nastronomers will continue to search for, including how galaxies
\nmerge and evolve<\/a>,
\nas well as the nature of the
\ndark matter<\/a>
\nthat galaxies reside in.<\/p>\n
