The European Space Agency's ISO space telescope has detected the first known infrared-bright gravitational arcs, which are the distorted and magnified images of very faraway objects. The gravitational arcs seen by ISO are revealing some of the farthest objects ever detected in the infrared, and scientists believe they may be distant young galaxies in collision. They number more than thirty, and their distance falls close to the place and time of the Big Bang.
