May 14, 2014 · When a massive star collapses under its own gravity during a supernova explosion it forms either a neutron star or black hole. Magnetars are an unusual and very exotic form of neutron star.

So, how do magnetars form? It starts with a neutron star. These are created when a massive star runs out of hydrogen fuel to burn in its core. Eventually, the star loses its outer envelope and collapses. The result is a tremendous explosion called a supernova. During the supernova, the core of a supermassive star gets crammed down into a ball only ...
A couple of dozen known magnetars have been observed, and other possible ones are still being studied. Among the closest is one discovered in a star cluster about 16,000 light-years away from us. The cluster is called Westerlund 1, and it contains some of the most massive main-sequence stars in the universe. Some of these giants are so big their at...
However a magnetar is born, its incredibly powerful magnetic field is its most defining characteristic. Even at distances of 600 miles from a magnetar, the field strength would be so great as to literally rip human tissue apart. If the magnetar floated halfway between the Earth and the Moon, its magnetic field would be strong enough to lift metal o...

Aug 17, 2023 · A magnetar’s magnetic field is so strong, in fact, that it can crack open the star’s surface to release powerful bursts of energy that may be visible across billions of light-years.

Apr 8, 2021 · Forged in supernovae, magnetars are imbued with magnetic fields a trillion times clingier than refrigerator magnets, strong enough to split x-ray photons and stretch normal atoms into oblong shapes. When those fields tangle and snap, the star can vent vast amounts of energy, enough to launch a burst of radiation across the universe.
A magnetar is a type of neutron star with an extremely powerful magnetic field (~10 9 to 10 11 T, ~10 13 to 10 15 G). The magnetic-field decay powers the emission of high- energy electromagnetic radiation , particularly X-rays and gamma rays .
