Negative image of the GRB970508 field, near the north celestial pole, taken hours after a gamma-ray burst. A faint optical transient source (potential GRB counterpart), boxed, shows a redshift of ~0.8, indicating a billions of light-years distance, solving a long-standing distance scale controversy.
