Einstein Ring (field) Distant galaxy with gravitational lens
May 16, 2005
This photo shows a new, true colour image of an Einstein ring (upper centre of photo), first discovered at ESO in 1995. The ring, which is the stretched image of a galaxy far out in the Universe, stands out clearly in green, and the red galaxy inside the ring is the lens. The discovery image was very faint, but this new picture, taken with the VLT during the Science Verification Programme allows a much clearer view of the ring because of the great light-gathering capacity of the telescope and, not least, because of the superb image quality.
