Galaxy bunch are the largest gravitationally leap structure in the universe , keeping together hundreds of galaxies , dark matter , and intergalactic accelerator pedal . uranologist have now discovered that they also host the largest magnetised fields in the existence .

Such a discovery was possible by looking at the so - called receiving set relics , arc - similar feature of intergalactic plasm that   give off a lot of radio waves . Relics are influence by magnetic fields , and by studying its   radio expelling , astronomer can see more about them .

allot to a   paper , write inAstronomy & Astrophysics , the magnetic fields are   about the same specialty as the Milky Way ’s , but they   seem to be more regular and less chaotic . observation of four galaxy clusters have depict that the magnetic fields are as unwashed as the gas between the galax in the cluster .

“ We discovered the so far largest ordered magnetic fields in the universe , extend over 5 - 6 million light - age , ” lead author Maja Kierdorf , from the Max Planck Institute for Radio Astronomy ( MPIfR ) , said in astatement .

The astronomers lay down the strength of the magnetic fields , and while they are millions of times weaker than a unwashed fridge attraction , they stretch over region 100 times the size of the Milky Way .

The galaxy clusters that host these magnetic fields formed by the coming together of pocket-sized groups of beetleweed .   The team approximate that the clusters combine at   velocities in high spirits than 2,000 kilometers per second ( 4.5 million mph ) , which is greater   than what was antecedently estimated using data from X - shaft observatories .

Radio keepsake have been chance on in about 70 galaxy clusters so far , and these particular reflection were conducted with the Effelsberg telescope , a 100 - meter ( 330 - metrical unit ) ravisher located in Germany .

“ The Effelsberg radio telescope proved again to be an idealistic instrument to detect magnetic study in the universe , ” sum up cobalt - author Rainer Beck , also from MPIfR.   “ Now we can systematically search for ordered magnetic fields in galaxy bunch using polarized radiocommunication undulation . ”

It ’s possible that prominent charismatic fields exist   out there , some even bigger than the   coltsfoot clusters that bring forth them .
