Description

Last year I captured this in the traditional Hubble Palette. While I love the Hubble Palette in all of it's tonality, I also like the natural look of my BiColor process. I reprocessed my data into this BiColor palette.

Melotte-15 is the star cluster at the heart of the Heart Nebula. It is an OB association of very young hot blue supergiant stars that is only 1.5 million years old. Fierce stellar winds from this cluster have blown the enormous bubble within the parent HII nebula that is the heart nebula. The winds have also sculpted the dust clouds within which other stars are forming into interesting columns and shapes, analogous to the Pillars of Creation in the Eagle Nebula.
