An out ring of baby stars burn brightly in infrared around a Congress of Racial Equality of cooler , elder stars . A faint S - bar in the halfway identifies NGC 1291 as a barred galaxy .
At 33 million light old age away , galaxy NGC 1291 has had 12 billion geezerhood for stars to bolt up debris and burn through their fuel . When it was new , stellar bars drove gas towards the nerve centre , enhancing ace - birthing rates . As theSpitzer Space Telescope press release explain :
Over time , as the star - making fuel ladder out , the cardinal area become quiescent and star - shaping activity shifts to the outskirt of a galaxy . There , spiral density waves and reverberance induced by the central bar help convince flatulency to mavin . The prohibited ring , see here in red , is one such sonority location , where gas has been pin and catch fire into a virtuoso - forming hysteria .
In this infrared image , blistering dust shine at 8.0 micron are colorise red , while wavelength 4.5 micron is green and 3.4 microns is in blue .
