| 41. | "You can expect a dangerous gamma ray burst every few hundred million years, " he said.
|
| 42. | This process is considered a possible explanation for a source of energy of such energetic phenomena as gamma ray bursts.
|
| 43. | But recent observations have led scientists to believe their theories are on target in linking black holes to gamma ray bursts.
|
| 44. | During the conference, several scientists reported that the tremendous energies of gamma ray bursts make them both mysterious and useful.
|
| 45. | What are known as gamma ray bursts are brief flares of intense energy that appear suddenly and randomly in deep space.
|
| 46. | Since military satellites first discovered them in the 1960s, scientists have detected more than 2, 000 gamma ray bursts.
|
| 47. | In visible light alone, Woosley said, the gamma ray burst energy was equal to about 1, 000 supernovae.
|
| 48. | The Buffalo Astronomical Association team had been alerted by Internet postings that spacecraft had detected a gamma ray burst near Hercules.
|
| 49. | They are able to have rapid and simultaneous multi-wavelength observations of gamma ray burst afterglows and other transient objects.
|
| 50. | A month after it was detected, the Large Binocular Telescope observed a 26th magnitude optical afterglow from the gamma ray burst
