The Elephant Trunk Nebula is a portion of interstellar gas and dust in the IC1396 ionized gas region, located in the constellation Cepheus, about 2,400 light-years from Earth.
The Elephant Trunk Nebula is now considered to be the site of star formation, which contains very young (less than 100,000 years old) stars found in infrared images in 2003. Two stars slightly older than these are housed in a small circular chamber at the head of the sphere. It is thought that the wind from these young stars changed the gas near them and created a cavity in the cloud we see.
The combined action of light from the giant star ionizes and compresses the rim / rim of the cloud, and the wind from the young stars pushes the gas out of the center, leading to very high compression and the formation of rheumatoid arthritis in the shape of an elephant’s trunk. And persuades the buyer.
