NGC 3313

NGC 3313 is a large barred spiral galaxy[2][3] located about 55 megaparsecs (180 million light-years) away in the constellation Hydra.[4] It was discovered by astronomer Ormond Stone in 1886[5][6] and is an outlying member of the Hydra Cluster.[7]

Physical characteristics

NGC 3313 has a complete inner ring feature that is elongated along the bar axis of the galaxy. Inside the inner ring, there are two weak dust lanes in the bar, and surrounding the nucleus there is a very circular nuclear ring. Spiral structure breaking off from the ring region has a complex structure and is tightly wrapped around the ring. The arms trail out into the outer disk where they from a well-defined two-armed pattern. The two-armed pattern also appears to take the form of an R1' outer pseudoring. Beyond this two-armed pattern, there are numerous spiral segments which extend to much larger distances.[3]
