This long, thin filamentary structure is located near the center of our Galaxy. These filaments run in the direction perpendicular to the plane of the Milky Way Galaxy and extend over a distance of greater than 50 light years. These filaments are influenced by the magnetic field. The semi-circular feature in the upper right hand part of the image is called the "Sickle" and is thought to be interacting with the magnetic filaments. Much of the nature of the filaments continues to remain a mystery to astronomers.
