Hubble Serves Up a Holiday Snow Angel

Hubble Serves Up a Holiday Snow Angel Tube. Duration : 0.75 Mins.


DECEMBER 15, 2011: The bipolar star-forming region, called Sharpless 2-106, or S106 for short, looks like a soaring, celestial snow angel. The outstretched "wings" of the nebula record the contrasting imprint of heat and motion against the backdrop of a colder medium. Twin lobes of super-hot gas, glowing blue in this image, stretch outward from the central star. This hot gas creates the "wings" of our angel. A ring of dust and gas orbiting the star acts like a belt, cinching the expanding nebula into an "hourglass" shape. This movie presents a visualization of the star-forming region known as S106. This unique three-dimensional view illustrates and emphasizes that many of the objects contained within astronomical images are not at the same distance, but, in fact, spread across light-years of space. The Hubble image is augmented with additional field-of-view from the Subaru Infrared Telescope. The stars and the lobes of glowing gas from the Hubble/Subaru two-dimensional image have been separated and sculpted using both scientific knowledge and artistic license to create the depth in the movie. Of note, the relative distances between stars and the nebula have been greatly compressed. The format of this movie is a standard "2D" presentation and does not require a 3D screen or 3D glasses.
