 The Elephant’s Trompe is perfectly recognizable by its shape. It is an obscure nebula contained in the nebula by IC 1396, itself immersed in the heart of a young star cluster.

In astronomy, dark nebulae, obscure nebulae or absorption nebulae are regions where the dust of the interstellar medium seems to be concentrated in large opaque clouds in the visible domain, which are therefore to our eyes as star-poor regions.

Whereas in reality, it is in the inner regions of these dark nebulae that star formation occurs, by gravitational collapse.

The Trumpet Nebula is located about 3000 light years from Earth in the constellation of Cepheus. It is 3 to 5 times the diameter of the full moon in the Earth’s sky. The Trumpet is more than 20 light-years long.
