Heart and Soul Nebulas


Located in the Perseus Arm of the Galaxy, the Heart nebula (left) and the Soul nebula (right) are two bright nebulae (although a telescope is needed to see them) in a region of the Galaxy where a lot of stars are forming. IC 1805 (the Heart nebula) is also sometimes called the 'Running Dog nebula' because it is said to resemble a running dog when viewed through a telescope. The distance to these two nebulae are well determined, mainly because they have star clusters at the centre of them. (It is much easier to determine the distance to a nebula if it has star clusters in it). The Heart and Soul nebulae are located in the Perseus Arm of the Galaxy 6000 and 6500 light years away. This part of the Perseus Arm has a lot of star formation regions and there are many young star clusters in this region.
