TED: A rare galaxy that's challenging our understanding of the universe | Burcin Mutlu-Pakdil

The transcript discusses the discovery of a rare galaxy that challenges existing theories about galaxy formation and evolution. The majority of galaxies are spiral, but rare types like Hoag's Object and the newly discovered Burçin's Galaxy present unique features that are not well understood. Burçin's Galaxy, located 359 million light years away, has an additional diffused inner ring, unlike any known galaxy. This discovery highlights gaps in our knowledge and emphasizes the need for further research to understand galaxy evolution and the universe better.

Why is Burçin's Galaxy considered one of the rarest types of galaxies?
