Explanation:
These
cosmic dust clouds drift
some 1,300 light-years away along the
fertile starfields of the constellation Cepheus.
The beautiful Iris Nebula,
also known as NGC 7023, blossoms at the upper left.
Not the only nebula in the sky to evoke the imagery of flowers,
its pretty, symmetric form spans about 6 light-years.
This nebula's dominant blue color is characteristic of
the pervasive dust grains reflecting light from a nearby hot, bluish star.
But darker, obscuring dust clouds cover
most of the nearly 4 degree wide field of view.
At
the right is the LDN 1147/1158 complex of
Lynds Dark Nebulae.
Stars are forming there, still hidden
within the dark cloud cores.
A search through the sharp image can identify
Herbig-Haro objects
though, jets of shocked glowing gas emanating from recently formed stars.
