This tadpole-shaped nebula is known as CG12. It is an example of a “cometary globule,” where a denser region of dust trails off into thread-like strands. While challenging to see in visible light images, WISE easily shows the full extent of the globule’s tail as it lights up at longer wavelengths of infrared light.

The tip of CG12 is also known as NGC 5367 in the Centaurus constellation. This region is easier to see as a “reflection nebula” as the light of the bright stars scatters off of the enveloping dust clouds, showing up in visible light images as a blue haze.

This image uses data from the original cryogenic phase of the WISE mission. Infrared wavelengths of 3.4 & 4.6 microns are displayed in blue and cyan, respectively, and are dominated by the glow of stars. Light with a wavelength of 12 microns is displayed in green and traces the presence of carbon-rich dust known as polycyclic aromatic hydrocarbons (PAHs). The 22 micron light is rendered in red and is dominated by the thermal glow of warm dust.
