This video opens with a backyard view of the nighttime sky centered on the constellation Cygnus, the Swan. We zoom into a vast donut-shaped feature called the Veil Nebula. It is the tattered expanding bubble of debris from a star that exploded about 8,000 years ago. The bubble has expanded to a diameter of roughly 110 light-years. Our zoom continues down to a two-light-year-wide segment of the nebula as photographed by the Hubble Space Telescope. Hubble resolves tangled rope-like filaments of glowing gases.
