Even our own Milky Way Galaxy is thought to have a bar , but perhaps not so prominent as the one in NGC 1365, shown above . The persistence and motion of the bar imply relatively massive spiral arms . The placements of bright young blue stars and dark dust lanes also indicate a strong rotating density wave of star formation. NGC 1365 is a member of the Fornax Cluster of Galaxies . Because NGC 1365 is relatively nearby, simultaneous measurements of its speed and distance are possible, which help astronomers estimate how fast our universe is expanding .
