This has been particularly exciting as new unexpected phenomena involving these stars continue to be discovered. Some are extraordinarily efficient accelerators for extremely relativistic particles and gamma-ray emission. Magnetic fields on neutron star surfaces are observed to range from less than a billion Gauss to more than a million times larger. Within our galaxy there are young strongly magnetized neutron stars which support repeated explosions. There is reason to suspect that distant ones near the edge of the observable universe may the source of extraordinary explosions in which perhaps a tenth of their reat mass energy is converted to bursts of gamma-rays.
Observations are far ahead of theories and much remains to be understood.
