NGC 588 is a prominent, giantH IIionized[5]diffuse nebula located in the outskirts of thegalaxyMessier 33's spiral arms, within theTriangulum constellation.[6][4] Thenebula has twoWolf-Rayet stars,NGC 588-UIT 008 andNGC 588-MC3 and a fairly large population ofmain sequence stars of 2 to 20 solar masses. The more massivestars in thenebula have a mass of around 40 solar masses. NGC 588 is 4.2 million years old and has amass of 2300solar masses.[7]
NGC 588 and NGC 592 (anothernebula in the Triangulum galaxy) are both very prominentstellar nurseries in their regions.[7]
It was discovered October 2, 1861, by the German–Danish astronomerHeinrich d'Arrest.[8]
