In the Center of NGC 6559
30 June 2004 
;newWindow.focus())
" Explanation:
Bright gas and dark dust permeate the space between
stars in the center of a nebula known as
NGC 6559. The gas, primarily
hydrogen, is responsible for the diffuse red glow of the
emission nebula. As energetic light from neighboring stars ionizes
interstellar hydrogen,
protons and electrons recombine to emit
light of very
specific colors, including the
red hue observed. Small dust particles
reflect blue starlight efficiently and so creates the blue
reflection nebulosity
seen near two of the bright stars. Dust also absorbs visible light, causing the
dark clouds and
filaments visible. NGC 6559 lies about 5000 light-years away toward the constellation of Sagittarius."
Imagine if we lived much closer to this, and we saw this view when we
looked up at night (assuming there was no light pollution). I'd be quite sure, that either we'd be completely nuts about gods, or we'd be flying about in space ships by now.
