Alice Shapley, a member of the team from UCLA, says, “Among the irregular and clumpy galaxies of the early Universe, this well-ordered spiral stuck out like a sore thumbâ€"a beautiful and amazing sore thumb.” The astronomers are still unsure how the spiral structure could have formed at such a young age, speculating that a nearby dwarf galaxy may be providing the gravitational tidal forces necessary to sweep out the larger galaxy’s spiral arms.Hubble continues to amaze astronomers by continuing to reveal stunning images of our Universe. According to NASA, Hubble is the first major optical telescope to be placed in space.
