Spiral Galaxy NGC 1084
This new Hubble image displays an almost face-on view of the galaxy NGC 1084, a spiral galaxy with no bar-shaped structure of stars at its center. Spiral galaxies lacking a central bar make up about half of all such galaxies. Astronomers have observed five supernova explosions which took place in NGC 1084 over the past half century. The supernova remnants bear names reflecting the year in which they took place: 1963P, 1996an, 1998dl, 2009H and 2012ec.
