A magnetar is a rare and powerful type of neutron star with an exceptionally strong magnetic field, ranging from 1013 to 1015 Gauss. They are considered the most magnetic objects in the universe, with fields millions of times stronger than the sun's. Here's a quick overview of magnetars:
Formation The stellar process that leads to a magnetar can take billions of years. Recent research suggests that less massive stars can become magnetars under the right conditions.
Structure Magnetars are neutron stars, which are the dead remnants of stars and are made entirely of neutrons.
Magnetic field A magnetar's magnetic field begins to decay after about 10,000 years.
Lifespan Magnetars have a short cosmic life, but scientists estimate there may be up to 30 million inactive magnetars in the Milky Way.
