In contrasting the distribution of the X-ray and gamma-ray bursts, we find:
A)gamma-ray bursts are far closer to us, so they appear more luminous.
B)gamma-ray bursts are far beyond our Galaxy, at cosmological distances, and spread all overthe sky, not in the plane of our Galaxy.
C)gamma-ray bursts are more closely associated with open than globular clusters.
D)gamma-ray bursts can repeat, while the X-ray bursts do not.
E)gamma-ray bursts can be observed from the ground, but X-rays are blocked by the ionospherefor ground-based observers.

Question

Quizplus · Accepted Answer

Gamma-ray bursts are located at cosmological distances, meaning they are far beyond our Galaxy and spread all over the sky, not concentrated in the plane of our Galaxy like the X-ray bursts. Gamma-ray bursts are observed to be at cosmological distances, indicating that they originate far beyond our galaxy. They are also observed throughout the sky, not specifically in the plane of our galaxy. In contrast, X-ray bursts are typically associated with neutron stars in our own galaxy and are not observed at cosmological distances.
