The Heart & Soul Nebula!
The Heart Nebula, IC 1805, Sharpless 2-190, is some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia.
It was discovered by William Herschel on 3 November 1787. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes.
At the center of the heart is open cluster of stars, known as Collinder 26 or Mellotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are
only a fraction of our Sun’s mass. At the very bottom of the Heart is the Fish-head Nebula, separately classified as NGC 896, because it was the first part of the nebula to be discovered.
W5 or the Soul nebula (aka Baby Nebula)
Westerhout 5 (Sharpless 2-199, LBN 667, Soul Nebula) is an emission nebula located in Cassiopeia. Several small open clusters are embedded in the nebula:
CR 34, 632, and 634 (in the head) and IC 1848 (in the body). The object is more commonly called by the cluster designation IC 1848.
Small emission nebula IC 1871 is present just above the top of the head, and small emission nebulae 670 and 669 are just below the lower back area.
W5 is a radio source within the nebula, spans an area of sky equivalent to four full moons and is about 6,500 light-years away in the constellation Cassiopeia.
Like other massive star-forming regions, W5 contains large cavities that were carved out by radiation and winds from the region’s most massive stars.
