  2. Veil Nebula - Wikipedia

    en.wikipedia.org/wiki/Veil_Nebula

    At the estimated distance of 2400 light-years, the nebula has a radius of 65 light-years (a diameter of 130 light-years). The thickness of each filament is 1 ⁄ 50,000 th of the radius, or about 4 billion miles, roughly the distance from Earth to Pluto. Undulations in the surface of the shell lead to multiple filamentary images, which appear ...
