This carved-out cloud of gas and dust has been nicknamed the "Jack-o'-lantern Nebula" because it looks like a cosmic hollowed-out pumpkin. Powerful outflows of radiation and particles from a massive star — known as an O-type star and about 15 to 20 times heavier than the Sun — has likely swept the surrounding dust and gas outward, creating deep gouges in the cloud. The image shows infrared light (which is invisible to the human eye) captured by NASA's Spitzer Space Telescope.
