This image shows the debris disc around the star 61 Virginis as seen with Herschel at far-infrared wavelengths.

61 Virginis is a G-type star that is known to host at least two planets, which have masses equivalent to about five and 18 times the mass of Earth and orbit their parent star at 0.05 and 0.22 AU, respectively – much closer than Mercury is to the Sun. The debris disc discovered with Herschel extends between 30 and 100 AU from the star – well beyond the orbits of its known planets.

The image is based on data gathered with the PACS instrument on board Herschel at wavelengths of 70 microns (blue), 100 microns (green) and 160 microns (red), respectively.
