Gravitational Lens System SDSSJ0946+1006 (Zoom onto Double Einstein Ring)

This is a zoom onto the Hubble Space Telescope Advanced Camera for Surveys image of gravitational lens system SDSSJ0946+1006, showing two concentric partial ring-like structures after subtracting the glare of the central, foreground galaxy.

About the colours

The image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope. A single filters was used to sample broad infrared wavelength ranges.
