G47 with Magnetic Streamlines

A long horizontal narrow orange cloud on a background of soupy brown and gray clouds. Magnetic field streamlines are laid over the orange cloud like stripes on a tiger's back.

A map shows the direction of magnetic fields in the G47 bone overlain atop an image of the G47 filament as seen by the Herschel Space Observatory. The red and yellow areas are high-density regions of dust and gas. Credit: G47: ESA/Herschel/PACS/SPIRE/Ke Wang et al. 2015; Polarization map: Stephens et al., 2021
