Sometimes scientists are also lucky. The astronomer of Yale University Imad Pasha was scanning some images on the ground when he came across a galaxy that boasted several rings. Since the name of the object, Leda 1313424, does not roll out of the language, his team nicknamed him Bullseye. This image of Hubble reveals why it is an appropriate moniker: the Galaxy boasts nine rings, you are more than any other known. The rings were formed as ripples in a pond after a blue dwarf galaxy torn the heart of Leda 1313424 about 50 million years ago. (The interloper appears just left in the center.) The collision triggered the birth of hot blue stars in the two external rings, while the redest interior rings accumulate near the center. The galaxy extends for 250,000 light years, 2.5 times the dimensions of the Milky Way and is located 570 million light years of distance in the constellation fish.
