The nearly 100 percent polarization of the radio bursts is unusual, and has only been seen in radio emissions from the extreme magnetic environments around massive black holes, such as those at the centers of galaxies. (sciencedaily.com)
«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.

We have been exploring Earth's magnetic environment for years using satellites such as ESA's Cluster mission, a fleet of four spacecraft launched in 2000. (sci.esa.int)
