▁has ▁a ▁greater ▁amount ▁of ▁gas ▁and ▁star ▁formation ▁than ▁the ▁host ▁ring . ▁This ▁likely ▁indicates ▁a ▁very ▁violent ▁formation . ▁The ▁polar ▁ring ▁contains ▁objects ▁number ing ▁in ▁the ▁hundreds . ▁Many ▁of ▁these ▁are ▁red ▁and ▁blue ▁super gi ant ▁stars . ▁The ▁most ▁recently ▁created ▁stars ▁in ▁the ▁ring ▁were ▁just ▁formed ▁approximately ▁ 7 ▁million ▁years ▁ago . ▁This ▁indicates ▁that ▁the ▁formation ▁of ▁these ▁stars ▁has ▁been ▁a ▁long ▁process ▁and ▁is ▁still ▁occurr ing . ▁ ▁Data ▁about ▁the ▁dark ▁matter ▁h alo ▁of ▁NGC ▁ 6 6 0 ▁can ▁be ▁extracted ▁by ▁obser ving ▁the ▁gravit ational ▁effects ▁of ▁the ▁dark ▁matter ▁on ▁the ▁disk ▁and ▁ring ' s ▁rotation . ▁From ▁the ▁core ▁of ▁the ▁disk , ▁radio ▁waves ▁are ▁being ▁em itted . ▁The ▁source ▁of ▁these ▁waves ▁is ▁an ▁area ▁only ▁ 2 1 ▁light ▁years ▁across . ▁This ▁may ▁indicate ▁the ▁presence ▁of ▁a ▁super - cluster ▁of ▁stars ▁located ▁within ▁an ▁area ▁of ▁cloud ▁of ▁gas . ▁The ▁region ▁in ▁the ▁centre ▁has ▁a ▁vast ▁amount ▁of ▁star ▁formation , ▁so ▁l umin ous ▁that ▁it ▁is ▁considered ▁to ▁be ▁a ▁star bur st ▁galax y . ▁ ▁Late ▁in ▁ 2 0 1 2 , ▁this ▁polar - ring ▁galax y ▁produced ▁an ▁enorm ous ▁out bur st ▁having ▁a ▁magnitude ▁of ▁approximately ▁ten ▁times ▁br ighter ▁than ▁a ▁super n ova ▁explos ion . ▁The ▁cause ▁is ▁not ▁certain , ▁but ▁this ▁event ▁may ▁have ▁resulted ▁from ▁a
