Herschel's test view of M51

Herschel's test view of M51

Date: 19 June 2009
Satellite: Herschel

A three-colour far-infrared image of M51, the whirlpool galaxy. Red, green and blue correspond to the 160-micron, 100-micron and 70-micron wavelength bands of the Herschel's Photoconductor Array Camera and Spectrometer, PACS.

Glowing light from clouds of dust and gas around and between the stars is visible clearly. These clouds are a reservoir of raw material for ongoing star formation in this galaxy. Blue indicates regions of warm dust that is heated by young stars, while the colder dust shows up in red.
