Nasa Hubble Space Telescope has snapped a spectacular view of a star-forming region in our Milky Way galaxy that looks like a snow angel in deep space. The bipolar star-forming region, called Sharples 2-106 (or S106 for short) is located nearly 2,000 light-years away in the direction of the constellation of Cygnus (The Swan). The nebula measures several light-years in length. It appears in a relatively isolated region of the Milky Way galaxy. Hubble’s view captures furious activity in the nebula, with ridges and ripples of super-hot gas mixing with the cooler interstellar medium. A massive young star, called Infrared Source 4 or IRS 4, is responsible for this turbulence. Radiation from IRS 4 makes the lobes of gas glow bright blue in the image, as they stretch outward from the central star.
Luminous red veins also appear throughout the nebula creating intricate patterns. A ring of dust and gas around the star squeezes the expanding nebula into its apparent hourglass shape. Faint light from the central star reflects off tiny dust particles, making the surrounding environment glow, and revealing darker filaments of dust beneath the blue dust clouds. Astronomers have studied S106 and found several hundred brown dwarfs, which are cool, failed stars. According to scientists when the nebula is viewed in infrared wavelengths, more than 600 of these misfit stars appear.
