Galaxy NGC 3384
This image, taken by the Hubble Space Telescope, shows galaxy NGC 3384, a typical example of an elliptical galaxy. These galaxies have a uniform spread of light, a round shape, few distinct features, and rarely show signs of new star formation. Instead, they are dominated by old, aging, red-colored stars. This is in sharp contrast to the liveliness of spiral galaxies like our own Milky Way, which have large numbers of young blue stars in spiral arms orbiting their bright center.
However, NGC 3384 also shows a hint of disk-like structure toward its center, in the form of a central "ribbon" of stars. Many spiral galaxies boast such a bar, including the Milky Way. These galactic bars are thought to help move material through and around the galactic core, sustaining and fueling the activities and processes that occur there.
