Description

Good afternoon everyone! Today's upload is Mellote 15, the central star cluster at the heart of the heart nebula. There are a few very bright stars here, with some of the most massive being around 50 times the mass of the Sun. The Heart Nebula and this cluster can be found in the constellation Cassiopeia, some 7500 light years away. The Heart nebula is a hydrogen two star forming region, and the stars in Mellote 15 were formed form the atomic hydrogen in the Heart Nebula. The cluster also contains many stars much smaller than our sun, and as time progresses, the largest stars in the cluster will begin to blow away the hydrogen gas with stellar winds, causing the nebula to take on more filementary shapes as the star cluster and nebula evolve together. The stellar winds causes gas to become more concentrated in certain areas, which will help in forming new stars later on. I hope you like today's image, and information. Be sure to check back tomorrow for a new upload, and Clear Skies!
