With the aid of the Hubble Space Telescope astronomers discovered this bipolar star-forming region in the Milky Way galaxy, called Sharpless 2-106. It looks like an angel spreading her wings. The nebula lies about 2,000 light-years from us, and it measures several light-years in length. It is heated by a young star, IRS 4 (= Infrared Source 4). The two lobes of super-hot gas, glowing blue in this image, stretch outward from the central star. This hot gas creates the 'wings' of the angel.
I wish all my followers a Happy and Peaceful Christmas Season!
