Heart Beats

My last blog post showcased a visit to the constellation of Cassiopeia where we looked at the beautiful pair, Heart and Soul Nebulas. Let’s take a closer look at the Heart Nebula (IC 1805). The nebula’s intense color and shape is said to be the result of radiation associated with a small group of stars near the nebula’s center. This small group of stars is well-known and designated as Melotte 15, otherwise affectionately known as the heart of the Heart Nebula. Melotte 15 contains a few bright stars that are in the range of 50 times the mass of the Sun… wow 😳 !

The brightest part of the nebula (located to the bottom right of the image) is designated as IC 1795: the Fishhead Nebula. Personally, it resembles a whole fish, but it is definitely an eye catcher. The Heart Nebula is known to be an active star forming region located approximately 7,500 light years from Earth
