Magnetic field of black hole measured
Pulsar near Milky Way’s center makes first assessment of this type possible

MAGNETIC STRENGTH The pulsar PSR J1745–2900 (left) sends out a beam of radiation in this illustration. By analyzing radio waves from the pulsar that passed through the galactic center, astronomers determined the strength of the magnetic field surrounding the Milky Way's supermassive black hole (right).
