Usatoday.com : The most likely explanation for what force could have permanently bent a ring in our Milky Way Galaxy within the last 60 million years appears to be a giant clump of dark matter.The dark matter is suspected to consist of enigmatic physics particles born in the fiery aftermath of the Big Bang and weighing as much as 10 million suns.Left behind by this cataclysm was a tilted swirl of newborn stars circling within the galaxy called the " Gould Belt ,” which incidentally may have sent comets hurtling towards Earth, suggests astrophysicist Kenji Bekki of Australia’s University of New South Wales in a recent Monthly Notices of the Royal Astronomical Society journal .
