A brand new magnetar found, it’s only 240 years old

Post by fred8615 »

Magnetars are some of the most ridiculous objects in the universe. Composed of the densest material possible spinning faster than your kitchen blender, they generate the absolute most powerful magnetic fields the cosmos has ever seen – and astronomers have recently spotted a newborn.

Neutron stars are made of the leftover cores of massive stars. In the final moments before the cataclysmic death of the parent star, billions upon billions of tons of plasma crush into the center at a healthy fraction of the speed of light. That intense crushing squeezes down the core to unimaginably high densities. Those densities – and the temperatures that go with them – are enough to shove electrons into protons, turning the core into a giant ball of neutrons.

And so, the death of a hydrogen-burning star gives rise to the birth of a neutron star, an object weighing a few times that of the sun crammed into a volume no bigger than your neighborhood. These beasts are composed of almost entirely all neutrons (hence the name) but contains enough leftover protons and electrons to generate ferocious magnetic fields.

And I mean ferocious. The magnetic fields found around the some neutron stars can top 100 million times the strength of the most powerful magnets made by humans. They are, indeed, the most powerful magnets in the known (and probably unknown) universe.

They are called the magnetars. And they are awesome.

AN INFANT PULSAR DEFIES CATEGORIZATION

Pulsars have historically been classified into different categories — but the distinction between them may be blurrier than we thought. The discovery of the youngest pulsar yet observed is now raising questions about how we classify these extreme objects.
