Astronomers have discovered the distant relatives of huge, highly organized magnetic filaments dangling in the center of the Milky Way
, offering a new clue. These magnetic filaments appear in pairs or clusters, sometimes even stacked and equally spaced. By comparing the distant filaments with his previous discovery, Zadeh and his colleagues have now suggested two possible explanations for the origin of these: from an interaction between large-scale wind and clouds or by turbulence inside a weak magnetic field.
."The underlying physical mechanisms for both populations of filaments are similar despite the vastly different environments. The objects are part of the same family, but the filaments outside the Milky Way are older, distant cousins — and I meanWith the Milky Way's black hole revealed, one big mystery still remains, Nobel Prize winner says
But understanding how these filaments formed took investigating the new population of filaments, located in a concentrated cluster of thousands of galaxies 1 billion light-years from. Particularly intriguing was that some of these galaxies are active radio galaxies that seem to be forming large-scale magnetic filaments.
In particular, the filaments in this cluster of galaxies are much larger than those in the Milky Way, between 100 and 10,000 times longer. Some of these extragalactic filaments are as long as 200, which is around 650,000 light-years. However, despite their larger size, the filaments in the galaxy cluster possess the same length-to-width ratio seen in the Milky Way's filaments, and both sets of filaments appear to transport energy in the same way.
