X-ray and Infrared Image of J1818 (IMAGE) Center for Astrophysics | Harvard & Smithsonian Caption This image contains an exceptional magnetar, a type of neutron star with very powerful magnetic fields. Astronomers have found evidence that this object may be the youngest known magnetar (about 500 years old in Earth's timeframe). It is also the fastest rotating one yet discovered (spinning about 1.4 times per second). This image shows the magnetar in X-rays from Chandra (purple) at the center of the image in combination with Spitzer and WISE infrared data showing the wider field of view. Magnetars form when a massive star runs out of nuclear fuel and its core collapses onto itself. Credit X-ray: NASA/CXC/Univ. of West Virginia/H.
