Wikipedia Description:<\/p>\n\n\n\n

IC 1590<\/strong> is an open cluster<\/a> located in the nebulosity of NGC 281<\/a>. 279 stars with magnitudes<\/a> less than or equal to 17 are visible within or near the cluster. The cluster is estimated to be 3.5 million years old,[1]<\/a><\/sup> making it relatively young compared to other star systems<\/a>. Inside the cluster is a multiple-star system that emits light which helps give the dust in NGC 281 its glow.[2<\/a><\/sup><\/p>\n\n\n\n

NGC 281<\/strong>, IC 11<\/strong> or Sh2-184<\/strong> is a bright emission nebula<\/a> and part of an H II region<\/a> in the northern constellation of Cassiopeia<\/a> and is part of the Milky Way<\/a>‘s Perseus Spiral Arm<\/a>. This 20\u00d730 arcmin<\/a> sized nebulosity is also associated with open cluster<\/a> IC 1590<\/a>, several Bok globules<\/a> and the multiple star, B 1. It collectively forms Sh2-184,[3]<\/a><\/sup> spanning over a larger area of 40 arcmin.[4]<\/a><\/sup> A recent distance from radio parallaxes<\/a> of water masers<\/a> at 22 GHz<\/a> made during 2014 is estimated it lies 2.82\u00b10.20\u00a0kpc (9200 ly) from us.[5]<\/a><\/sup> Colloquially, NGC 281 is also known as the Pacman Nebula<\/strong> for its resemblance to the video game character<\/a>.<\/p>\n\n\n\n
