G359.1-0.2 (short for G359.13142-0.20005), or more commonly known as "The Bone" or the Galactic Center Snake (or, more simply, The Snake), is a radio filament located in the Galactic Center of the Milky Way galaxy. It is one of the brightest radio filaments discovered and is also one of the longest at ~ in length; however, it is thin, being just in width.

It may have formed from a star trail intersecting a shock from a supernova remnant (SN) which preferentially travelled up the trail accelerating electrons producing radiation.

Morphology The snake is one of the longest radio filaments discovered so far but it is very thin, being about 0.4 parsecs wide. Running along it are two kinks, a major northern kink and a southern minor kink. The major kink is likely produced by a pulsar moving between through the filament.

It is linearly polarized over much of the filaments extent. The intrinsic magnetic field is also well aligned.

Environment Located to the west of The Snake’s both major and minor kinks are two compact radio objects named G359.132-0.200 (a radio pulsar) and G359.120-0.265.
