IC 1396: Emission Nebula in Cepheus
Explanation: Stunning emission nebula
IC 1396 mixes glowing cosmic gas and dark dust clouds in the
high and far off constellation of Cepheus. Energized by the bright central star seen here, this
star forming region sprawls across hundreds of light-years, spanning over three degrees on the sky while nearly 3,000 light-years from planet Earth. Among the intriguing
dark shapes within IC 1396, the winding
Elephant's Trunk nebula lies just below center. Stars could still be forming inside the dark shapes by gravitational collapse. But as the denser clouds are eroded away by powerful stellar winds and radiation, any forming stars will ultimately be cutoff from the reservoir of star stuff.
The gorgeous color view is a composition of image data from narrowband filters, mapping emission from the nebula's atomic oxygen, hydrogen, and sulfur into blue, green, and red hues.

NGC 3576, the Statue of Liberty Nebula.

There are some similarities between the Statue of Liberty and the Elephant Trunk Nebula in IC 1399, but it is NGC 3576 that is commonly known as the Statue of Liberty Nebula.

<<The Motherland Calls (Russian: Родина-мать зовёт!) is a statue in Mamayev Kurgan in Volgograd, Russia, commemorating the Battle of Stalingrad. It was designed by sculptor Yevgeny Vuchetich and structural engineer Nikolai Nikitin, and declared the largest statue in the world in 1967. Today, it is the tallest statue in Europe and the tallest statue of a woman in the world, not including pedestals. The monument was inspired by the Ancient Greek sculpture the Winged Victory of Samothrace, and was modelled on a local woman, Valentina Izotova.>>
