In the vast expanse of the constellation Cygnus, about 2000 light - years from Earth, lies a remarkable star - forming region centered around the young star S106 IR. The powerful radiation emitted by this star has enabled the Hubble Space Telescope to capture an image of the surrounding gas and dust, which strikingly resembles a celestial snow angel, a sight that has captivated astronomers and space enthusiasts alike.

The star S106 IR, a massive entity with a mass estimated to be around 15 times that of the Sun, is only about 100,000 years old. Its intense radiation ionizes the nearby gas, creating an emission nebula. The ionized gas glows brightly, with the characteristic blue hue from ionized hydrogen prominent in the Hubble image. This hot gas streams outwards, forming twin lobes that resemble the outstretched wings of an angel. Meanwhile, a disk of dust and gas orbiting S106 IR, visible as a brownish band near the image center, gives the overall nebula an hourglass - like or butterfly - shaped appearance, as if the disk is cinching the expanding nebula in the middle.
Farther from the central star, the dust particles play a different role. They reflect the light from S106 IR, acting as a reflection nebula. This combination of emission from the ionized gas and reflection from the dust creates a complex and beautiful interplay of light and color. Moreover, detailed analysis of infrared images of this region has revealed the presence of over six hundred brown dwarfs lurking within the nebula's gas. These brown dwarfs, often referred to as "failed stars" due to their inability to sustain nuclear fusion like our Sun, add another layer of intrigue to this already fascinating cosmic landscape. The S106 star - forming region, with its unique shape and dynamic processes, serves as a crucial area for scientists to study the early stages of star formation and the complex interactions between young stars, gas, and dust in the universe.
