The experiment made nine trips into the stratosphere for a total flight time of 223 hours.

On Feb. 28, 1997, moments after a GRB was detected, BeppoSAX turned its X-ray telescopes to the location and spotted an X-ray afterglow -- the first GRB observation in a wavelength other than gamma rays. The satellite's accurate positions, together with other observations, showed that GRBs originate beyond our Milky Way galaxy.

Colored fields represent a component of the curvature of space-time. The outer red sheets correspond directly to the outgoing gravitational radiation detected by gravitational-wave observatories. The brighter yellow areas near the black holes do not correspond to physical structures but generally indicate where strong non-linear gravitational-field interactions are in play. Credit: NASA/C.
