masses like giant black holes or clusters of galaxies warp and deflect light
coming from behind them. “Point” sources appear as arcs. When the source and
deflector are properly aligned, the arc can be a closed circle – an Einstein
Ring. The Sun's deflection of starlight is a small scale example of
what becomes large scale when clusters of galaxies are the deflecting matter.</span></i><span style="font-size:14pt;font-weight:normal;">
