Elephant's Trunk Nebula (IC 1396A), optical image. IC 1396 is a giant emission nebula that is illuminated by a hot, massive O-type star (HD 206267) near its center. The star is not visible in this image (it is off the top edge of the image). This image shows IC 1396A, a dark, dense cloud of gas embedded in the nebula. It is known as the 'Elephant Trunk Nebula' because of its distinctive shape. The predominant red colour is due to hydrogen alpha emissions. This nebula is around 2400 light years from Earth, in the constellation of Cepheus. This image was obtained with the wide-field view of the mosaic camera on the Mayall 4-meter telescope at Kitt Peak National Observatory.
