This is the Southern Ring Nebula seen as never before in Near Infrared (left) and Mid Infrared (Right). Identify the most significant observation of the above image from the below options.
The central star is running out of fuel and hence shining so bright diffusing dust and matter into space.
Two stars are tightly in an orbit, and the brighter star influencing the nebula's appearance. The dimmer star losing its atmosphere due to the influence of its counterpart.
The counterpart of the main bright star is running out of fuel and hence not visible in Near infrared.
Both the stars will eventually collide into a supernova destroying the nebula leaving behind supernova remnants.
