The discovery of these puzzling objects and speculation on
their characteristics will be discussed in the March 23 issue of
Nature magazine. The findings are from NASA’s Compton Gamma Ray
Observatory (CGRO) spacecraft.

The Space Science Update panelists will be:
* Dr. Donald Kniffen, CGRO deputy program scientist, NASA
* Dr. Neil Gehrels, CGRO project scientist, NASA Goddard Space
Flight Center, Greenbelt, MD

University of Paris VII, Commission of Atomic Energy, Saclay,
* Dr. Lynn Cominsky, Professor, physics and astronomy, Sonoma
State University, CA

The event will be carried live on NASA Television with
question-and-answer capability for reporters covering the briefing
from participating NASA centers. NASA television is broadcast on
satellite GE-2, transponder 9C, at 85 degrees West longitude,
vertical polarization, frequency 3880 MHz, audio of 6.8 MHz.
