Since the late 1960s, scientists have puzzled over the cause of bursts of gamma ray energy that appear at random and without any apparent connection to known objects in the sky. With the Burst and Transience Source Experiment (BATSE) aboard the Compton Gamma Ray Observatory, scientists at NASA's Marshall Space Flight Center have recorded and analyzed almost 2,000 bursts since the CGRO's launch in 1991.
The results provide strong indications that these bursts originate from the remotest parts of the universe, at distances of billions of light years from Earth. These conclusions contradict theories that the bursts must somehow be associated within or just outside of our own Milky Way Galaxy.
In its January 1998 issue, Discover lists its Top 100 science stories for 1997. On page 30, writer Sam Flamsteed writes "It turns out they are truly titanic." This refers to the implication that if bursts are at cosmological distances, then each burst must release about as much energy in 10 seconds as our Sun emits in its entire lifetime.
In its Dec. 19 issue, Science notes that the discovery of optical counterparts - done by NASA/Marshall scientists - is a "mixture of good science and good luck [that] promises to open a new window on an intriguing mystery."
