The heart of the Soul Nebula

This image, taken by NASA's WISE infrared space observatory mission team, shows the Soul Nebula in a montage of color. The Soul Nebula is also known as the Embryo Nebula, IC 1848, or W5. "The Soul Nebula is an open cluster of stars surrounded by a cloud of dust and gas over 150 light-years across," says Space.com. "[It is] located about 6,500 light-years from Earth in the constellation Cassiopeia, near the Heart Nebula." In this image, you can almost see a human form within its center, two blue eyes beaming out from the center, or soul, of the cloud.
