If you are currently reading this from the comfort of your sofa , passive and presumed stationary , you are in fact whizzing through outer space at great stop number . The Earth rotates on itself , moves around the Sun , and the full Solar System moves with everything else in the Milky Way . Our galaxy actuate at an telling 210 kilometers ( 150 miles ) per moment but it is definitely not a criminal record - breaker amongspiral galaxy .
uranologist have discovered about 100super volute , disk wandflower that are larger , shiny , and more massive than the milklike Way . Now research worker live that they also spin much quicker , with the heaviest one , angle 20 times our coltsfoot , spin at about 570 kilometers ( 350 miles ) per secondly . The findings are reported inThe Astrophysical Journal Letters .
“ Super spirals are uttermost by many measures , ” lead generator Patrick Ogle of the Space Telescope Science Institute in Baltimore say in astatement . “ They erupt the records for rotation focal ratio . ”
These galax are not the giving galaxies in the universe , but they are the big spirals , and they do n’t seem to postdate an important principle . stargazer antecedently set up a human relationship between the quite a little of a volute galax and the speed at which it splay , but these tiptop coil do n’t seem to come after it ; they have n’t got enough stars for their speed .
According to the current model of the universe , five - one-sixth of the thing in the existence does n’t interact with light , only with graveness , hence " dark affair " . This dark thing observe galaxies in their shape by simply scatter out further than the visible matter , in what is call in the dark affair glory . In these super spirals , the nimbus is much heavier , comparable to what ’s usually found around a chemical group of beetleweed , rather than a individual one .
“ This is the first time we ’ve found spiral galaxy that are as big as they can ever get , ” Ogle order . “ It come along that the spin of a galax is set by the mass of its dark subject halo . ”
The findings tone up the idea that dark thing , which we are yet to find directly , is the correct theory to excuse the movement of galax . Alternative theories such as the Modified Newtonian Dynamics ( MOND ) want changes to how sobriety works and they would n’t be capable to explicate how super spirals can spin so fast .
research worker will be capable to investigate these galaxies further using the James Webb Space Telescope after it is establish in 2021 .
