NGC 7822 [SEP] constellation
NGC 7822
NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000
Nebula is an example of an unusual shape that an elephant trunk can assume. It has a double helix structure instead of the normal straight column. The double helix is caused by the presence of magnetic fields and electric currents lined up along the trunk axis of the trunks. This makes the filaments of the columns wavy instead of straight, as they are in normal trunks. These filaments wrap around each other rather than line up next to each other, which forms the twisted structure.
