THE MOST DISTANT GAMMA RAY BURST, at a red shift of 3.4, was discovered in December and observed at several wavelengths. Optical measurements (yielding a red shift) of the object made with the Keck Telescope and the Hubble Space Telescope were announced by Caltech astronomer Shrinivas Kulkarni at last week's APS/AAPT meeting. Optical astronomers were led to the burst's spot in the sky by x-ray observations made by the BeppoSax satellite. (Science, 24 April 1998.)
