Scientists have hotly debated whether the bursts are cosmological -- from the edge of the universe -- or galactic, from within the Milky Way. Now we have strong evidence that most gamma ray bursts come from within our galaxy, Lamb said. The 25-year-old question about where the bursts originate may finally be answered.. Lamb said the evidence that the bursts are galactic in origin was a surprise, and certainly not something I was confident of initially..
Indeed, the discovery of pulsars in 1967 first suggested that neutron stars exist. Gamma-ray bursts may be produced from rapidly rotating, high-mass stars that collapse to form a neutron star, or from the merger of binary neutron stars.eutron stars are the densest and smallest stars known to exist in the universe; with a radius of only about 12â13 km (7 mi), they can have a mass of about twice that of the Sun.
