From the Ted Talk by Burçin Mutlu-Pakdil: A rare galaxy that's challenging our understanding of the universe

Unscramble the Blue Letters


There are more than a trillion galaxies in the universe. And my team discovered an elxemrety rare one, a galaxy that doesn't look quite like anything observed before. This galaxy is so peculiar, that it challenges our theories and our assumptions about how the universe works.

The majority of the gelixaas are spiral, similar to our own Milky Way. We have strong theories about how these common galaxies form and evolve. But we don't understand how rare galaxies form and evolve. An especially pliuzzng rare case is Hoag's oecbjt. It has a very symmetric central body surrounded by a circular oteur ring, with nothing vilbise connecting them. Hoag-type galaxies are among the rarest types of galaxies currently known. There are fewer than one in 1,000 galaxies. It's a mystery how the stars in the outer ring are just floating there in such an orderly manner. That's interesting, right? Hold on. Things are about to get more mysterious.

There are more than a trillion galaxies in the universe. And my team discovered an extremely rare one, a galaxy that doesn't look quite like anything observed before. This galaxy is so peculiar, that it challenges our theories and our assumptions about how the universe works.

The majority of the galaxies are spiral, similar to our own Milky Way. We have strong theories about how these common galaxies form and evolve. But we don't understand how rare galaxies form and evolve. An especially puzzling rare case is Hoag's Object. It has a very symmetric central body surrounded by a circular outer ring, with nothing visible connecting them. Hoag-type galaxies are among the rarest types of galaxies currently known. There are fewer than one in 1,000 galaxies. It's a mystery how the stars in the outer ring are just floating there in such an orderly manner. That's interesting, right? Hold on. Things are about to get more mysterious.
