Planck sees tapestry of cold dust

Dust structures within 500 light-years of the Sun.

This new image from the Planck spacecraft shows giant filaments of cold dust stretching through our galaxy. The image spans about 50 degrees of the sky, showing our local neighborhood within approximately 500 light-years of the Sun. “What makes these structures have these particular shapes is not well understood,” says Jan Tauber, ESA Project Scientist for Planck. Analyzing these structures could help to determine the forces that shape our galaxy and trigger star formation.
