This is an artist's depiction of an extremely rare magnetar, a neutron star spinning at incredible speeds and emitting incredible amounts of x-rays. The star is so dense, the entire mass of sun is fit into an object with a mere 9 mile radius. A spoonful of material from this magnetar would literally weigh many tons.
This star, located 1500 light years away in the constellation Sagittarius, has the strongest magnetic field of anything in known universe: 600 trillion times stronger than Earth's magnetic field.
