This is an AAS-level poster that describes some of CGRO's most exciting scientific accomplishments. Three results are given for each of the four instruments in the form of an image plus an explanatory caption. These were contributed by members of the instrument teams. The poster was designed by Carol Ladd at the Graphics Department at Goddard Space Flight Center. Larger images of the poster and its contents can be viewed by clicking on the thumbnail images below.

Poster Content
The Compton Gamma Ray Observatory has studied the gamma-ray
sky from 15 keV to 30 GeV since its launch in 1991.
BATSE
Demonstrated that gamma-ray burst sources are distributed in a manner consistent with a cosmological population. |
Monitoring of hard X-ray sources and searching for new transients via Earth occultation. |
Discovery of soft gamma repeater SGR 1627-41. |
COMPTEL
Produced first-ever 1 to 30 MeV all-sky map. |
Produced all-sky map of 26Al emission with unprecedented quality. |
Observed neutrons from June 15, 1991 solar flare. |
EGRET

OSSE
First determination of spatially extended 511 keV annihilation line radiation from Galactic center region. |
|
Established that spectra of Seyfert galaxies have high-energy cutoffs above a few hundred keV. |
