More space news and info at: http://www.coconutsciencelab.com - zooming into the vast doughnut-shaped Veil Nebula, a tattered expanding bubble of debris from a star that exploded about 8,000 years ago. The bubble has now expanded to a diameter of roughly 110 light-years. The video continues with a 3-D visualization of a small portion of the Veil Nebula as photographed by the Hubble Space Telescope. The visualization model shows that the giant bubble of gas has a thin, rippled surface. It also highlights that the emission from different chemical elements arises from different layers of gas within the nebula. In the imagery, emission from hydrogen, sulfur, and oxygen are shown in red, green, and blue, respectively. Please rate and comment, thanks! Image Credits: NASA, ESA, and F. Summers, G. Bacon, Z.
