While reading the science news this morning (as I do every day) I saw a BBC article entitled "Mysterious 'iron bar' discovery in space may reveal Earth's future." We see a deep space picture of what looks like a giant striped blue orb, one with a red stripe, and a green gaseous ring around the blue part. The structure is larger than the size of our solar system.
As someone who has been avidly following astronomy news for much longer than half a century, I have a bit of skepticism about this story. The structure photographed is the Ring Nebula. I have been seeing photos of the Ring Nebula for most of my life, and they never showed a noticeable stripe-like structure in its center. Apparently the authors of the scientific paper have done some type of special processing to yield a red stripe in the middle of the blue circular center of the Ring Nebula. They claim that there's lot of iron in the stripe. We know what causes objects like the Ring Nebula (supernova explosions), but do not understand why any stripe or bar shape would arise in such an object.
I have a doubt or two about the analysis of the authors of this paper, but I do know one thing. I have personally photographed more than 65 mysterious striped blue orbs, which you can see using the link here, and continuing to press Older Posts at the bottom.
