Magnetars are a special class of neutron stars known for having the most powerful known magnetic fields in the Universe. They are incredibly dense and are made of tightly packed neutrons, formed from the collapsed core of a massive star during a supernova. Astronomers have recently discovered the fastest spinning and possibly youngest the magnetar known. Dubbed J1818.0-1607, it is located around 21,000 light years away from the Milky Way galaxy. New observations have revealed that this object is also a pulsar, as it emits regular pulses of light.
