J1713+0747

J1713+0747 is a pulsar—a rapidly rotating neutron star that emits regular beams of radio waves. It’s part of a binary system, paired with a white dwarf star. Its precise radio signals allow scientists to study extreme physics, test gravity's laws, and improve understanding of stellar evolution. Because its pulses arrive with extraordinary regularity, J1713+0747 serves as a natural cosmic timekeeping device, helping researchers detect phenomena like gravitational waves. Located roughly 4,000 light-years away in the constellation Serpens, J1713+0747 is one of the most precisely measured pulsars, vital for advancing astrophysics.
