A single gram of Ra-226 decays at the rate of … WebThe magnetospheres of some pulsars accelerate particles to such high energies that they are relatively bright gamma-ray sources. Astronomers have found less than 2,000 pulsars, yet there should be about a billion neutron stars in our Milky Way Galaxy. There are two reasons for this shortfall. One is age: most neutron stars are billions of years ...
