NGC 7023: The Iris Nebula

In mother nature (here on the Earth), the energy spent by real irises to attract pollinators is impressive. Wonderful colors and details attract and assist nectar-seeking guests. While there isn't a biological imperative for the Iris Nebula shown here, its color and detail certainly does invite anyone that searches the heavens to stop and take in this delicate vista. Pastel shades of blue and pink highlight the clouds of this celestial flower.
