Spellbinding Cosmic Beauty: Why Astronomy Images Matter

[ariete]

space has more colors than the depths of the earth's seas.
i belived coloured refraction is only due to the color of stars and clusters of matter and gas on which is reflected the lights, not that photos are retouched if not altered.

in last photo it seems earth lost his atmosphere. at the extremes we can see such wonders but maybe better an holyday in greece in summer, then is too much cheaper in these times.
