Chandra Image of PSR B1509-58 (image) Chandra X-ray Center Share Print E-Mail Caption At the center of this Chandra image, a pulsar -- only twelve miles in diameter -- is responsible for this X-ray nebula that spans 150 light years. This pulsar is spinning around almost 7 times a second and has a magnetic field at its surface estimated to be 15 trillion times stronger than the Earth's magnetic field. This combination of rapid rotation and ultra-strong magnetic field drives an energetic wind of electrons and ions, ultimately creating the elaborate nebula seen by Chandra. Credit NASA/CXC/SAO/P.
