description Seahorse Nebula Overview
The Seahorse Nebula, catalogued as Barnard 150, is a dark nebula in the constellation Cepheus. It appears as a long, sinuous silhouette because its cold interstellar dust blocks visible light from the dense background of Milky Way stars. The cloud contains several denser condensations associated with the Lynds designation L1082, making it useful to astronomers studying the structure and early gravitational evolution of nearby molecular clouds.
help Seahorse Nebula FAQ
What is the official astronomical designation for the Seahorse Nebula?
The Seahorse Nebula is cataloged as Barnard 150. It is a dark nebula located in the constellation Cepheus.
Why is Barnard 150 called the Seahorse Nebula?
It gets its name from its distinct, seahorse-like outline when viewed through long-exposure astrophotography. The opaque cloud of cosmic dust blocks out the light from background stars, creating this recognizable silhouette against the night sky.
What kind of celestial object is the Seahorse Nebula?
It is a dark nebula, which is a dense cloud of interstellar dust and non-luminous gas. These regions are thick enough to completely obscure the visible light from the stars and bright nebulae behind them.
Are there any notable star-forming regions associated with the Seahorse Nebula?
Yes, the Seahorse Nebula contains dense molecular cores cataloged by astronomers as L1082 A, B, and C. Researchers have studied these specific dense cores to observe the very earliest stages of star formation.
