Molecular cloud seen by Planck

Planck colour composite of the Rho Ophiuchus molecular cloud highlights the correlation between the anomalous microwave emission, most likely due to miniature spinning dust grains observed at 30 GHz (shown here in red), and the thermal dust emission, observed at 857 GHz (shown here in green). The complex structure of knots and filaments is striking evidence for current star formation. More Planck images available on ESA's Multimedia Gallery at
