Approximately 3000 light years distant near the central region of the galaxy and in the constellation Sagittarius is this bipolar planetary nebula designated NGC 6537 or the Red Spider. This dying star, now a white dwarf is likely in partnership with another star. That would explain the two-lobed butterfly appearance that we see. As the central star expels its outer layers the stars interior is now exposed which then showers the surrounding area to include its former material with ultraviolet radiation which then ionizes the material rendering it aglow.
