Ticking cosmic clocks reveal the evolution of stars over millions of years
Pulsars, a type of rotating neutron star, are well-known as incredibly stable astrophysical clocks. Their regularity, used to measure their radio pulses, has led to some of the most exciting tests of Einstein’s general theory of relativity and allowed scientists to examine the behavior of the extremely dense matter inside neutron stars.
