Using data from the CanariCam infrared camera on the Gran Telescopio Canarias, astronomers have created a high resolution
map of the magnetic field lines in gas and dust swirling around the supermassive black hole at the center of the Milky Way Galaxy.
In this way, nanoflares may also be the missing link responsible for untangling the chaotic
mess of magnetic field lines on the surface of the Sun, explaining why the corona has neat loops and smooth fans of magnetic fields.
You can
think of the magnetic field lines as wires in a titanic electric circuit, with the black hole as the generator, or you can think of them as elastic bands that literally fling electrically charged particles into distant space as they themselves are whipped around by the rotating black hole.
«We computed the Sun's magnetic environment by tracing
millions of magnetic field lines and looking at how neighboring field lines connect and diverge,» said Antonia Savcheva, an astrophysicist at the Harvard - Smithsonian Center for Astrophysics in Cambridge, Massachusetts, and co-author of the paper.
Similar to how water in a bathtub forms a whirlpool as it goes down a drain, the gas and magnetic fields that feed a supermassive black hole swirl to form a rotating disk — a tangled
spaghetti of magnetic field lines mixed into a broth of hot gas.
The magnetic sense in migratory birds has been studied in considerable detail: unlike a boy scout's compass, which shows the compass direction, a bird's compass recognizes the
inclination of the magnetic field lines relative to Earth's surface.
Both satellite and radar will investigate the phenomena that cause the aurora borealis, but from different
ends of the magnetic field lines that lead from space to the Earth's poles.
The MRX device produces laboratory studies of magnetic reconnection, the convergence and violent
separation of magnetic field lines in plasma, the state of matter that consists of free electrons and atomic nuclei.
If there is a strong magnetic field in the accretion disk, the magnetic field lines can be distorted into a tangled, narrow
mess of magnetic field lines that run toward the poles perpendicular to the accretion disk.
Using data from the CanariCam infrared camera on the Gran Telescopio Canarias, astronomers have created a high resolution
map of the magnetic field lines...
Jets are narrow streams of gas that emergefrom the cores of some galaxies, travel at more than 99 percent thespeed of light, and penetrate as much as several million light - yearsinto intergalactic space before fanning out into broad, luminous lobes.How might a black - hole whirlpool generate such a pair of waterspouts?Swirling bundles
of magnetic field lines, flinging particles outwardfrom the poles of the hole, provide a natural explanation.
