English 1a observation essay

On July 2, 1967, at 14:19 UTC , the Vela 4 and Vela 3 satellites detected a flash of gamma radiation unlike any known nuclear weapons signature. [8] Uncertain what had happened but not considering the matter particularly urgent, the team at the Los Alamos Scientific Laboratory , led by Ray Klebesadel , filed the data away for investigation. As additional Vela satellites were launched with better instruments, the Los Alamos team continued to find inexplicable gamma-ray bursts in their data. By analyzing the different arrival times of the bursts as detected by different satellites, the team was able to determine rough estimates for the sky positions of sixteen bursts [8] and definitively rule out a terrestrial or solar origin. The discovery was declassified and published in 1973 as an Astrophysical Journal article entitled "Observations of Gamma-Ray Bursts of Cosmic Origin". [9] This alerted the astronomical community to the existence of gamma-ray bursts (GRBs) , now recognised as the most violent events in the universe.
