NGC 613, a large elongated spiral galaxy

NGC 613 is an elongated barred spiral galaxy over 100,000 light-years across, located about 64 million light-years away in the southern constellation Sculptor. The outer tips of the spiral arms curve in opposite directions as if to show the direction of spiral motion.

In contrary to most barred spirals, NGC 613 has many arms that give it a tentacle-like appearance. It has a huge central bar, and radio emission indicates the presence of a massive black hole at the center of the galaxy. NGC 613 is laced with prominent cosmic dust lanes and bright star forming regions.

Studies of this galaxy in the radio wavelengths indicate that the nucleus is extremely active. And there is some evidence for an accelerated and collimated jet of gas being expelled from the center of the galaxy.

Astronomers studying this galaxy are interested in the processes that take place along the bar of the galaxy. One recent paper suggests that this galaxy could have two bar-like structures in its center.
