Forget the diamond rings, there are rings made of stars!!!
600 million light years away in the constellation Serpens lies this unusual-shaped galaxy called Hoag’s Object, which resembles a ring (made of hot, young, massive, blue stars) and a yellow nucleus (which composes of old stars) at it’s center. The width of this stellar ring (120,000 light-years wide) is actually larger than the width of our own Milky Way. In the gap between the blue ring and the yellow nucleus might reside many star clusters which are very faint to be seen.
Though ring-galaxies are very rare but in this image we have captured two of that kind. Look inside our ring at 1 o’clock position – we can actually see n the background of this ring, another perfect ring galaxy.
