Astronomers discover the lowest-mass double neutron star system to date
Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars, spin and send out beams of radio waves, making them appear to pulse as the beams sweep past Earth.
