The Iris Nebula
11/12/10
This picture shows clouds of interstellar gas and dust that have blossomed 1.300 light years away in the Constellation Cepheus known as the king. Cataloged as NGC 7023, it isn't the only nebula in the sky to evoke imagery of flowers. It's really awesome how you can see the different ranges of colors in so much detail! Infrared observation indicate that this nebula may contain complex carbon molecules known as PaHs. The Bright blue portion of the Iris Nebula is about six-light-years across.
