We present five band imaging of the Vega debris disc obtained using the Herschel Space Observatory .
These data span a wavelength range of 70–500 \mu m with full-width half-maximum angular resolutions of 5.6-36.9″ .
The disc is well resolved in all bands , with the ring structure visible at 70 and 160 \mu m. Radial profiles of the disc surface brightness are produced , and a disc radius of 11″ ( \sim 85 AU ) is determined .
The disc is seen to have a smooth structure thoughout the entire wavelength range , suggesting that the disc is in a steady state , rather than being an ephemeral structure caused by the recent collision of two large planetesimals .
