Quasar 1208+101 (gravitational lens candidate)

An image of the gravitational lens candidate taken with NASA/ESA Hubble Space Telescope's Wide Field and Planetary Camera (WFPC) in PC mode, on 23 December 1991. The HST picture shows that the quasar actually consists of two images. HST observations to be made this winter will show whether this is a gravitational lens or a chance superposition of a star in our own galaxy and a quasar. The bar in the lower left represents one arc second (the diameter of a penny seen at about two miles or 3.2 kilometres) which is the typical resolution of ground-based telescopes.

This image is being presented on Monday, January 13th at the 179th meeting of the American Astronomical Society in Atlanta, Georgia.
