NASA Astronomy Image of the Day for 10 July 2017

What's happening around the center of this spiral galaxy? Seen in total, NGC 1512 appears to be a barred spiral galaxy -- a type of spiral that has a straight bar of stars across its center. This bar crosses an inner ring, though, a ring not seen as it surrounds the pictured region. Featured in this Hubble Space Telescope image is a "nuclear ring" -- one that surrounds the nucleus of the spiral. The two rings are connected not only by a bar of bright stars but by dark lanes of dust. Inside of this nuclearring, dust continues to spiral right into the very center -- possibly the location of a large black hole. The rings are bright with newly formed stars.
