NGC 588 is a prominent, giant H II ionized[5] diffuse nebula located in the outskirts of the galaxy Messier 33's spiral arms, within the Triangulum constellation.[6][4] The nebula has two Wolf-Rayet stars, NGC 588-UIT 008 and NGC 588-MC3 and a fairly large population of main sequence stars of 2 to 20 solar masses. The more massive stars in the nebula have a mass of around 40 solar masses. NGC 588 is 4.2 million years old and has a mass of 2300 solar masses.[7]
