The Ring Nebula is about 2,000 light-years from Earth and measures roughly 1 light-year across. Located in the constellation Lyra, the nebula is a popular target for amateur astronomers. Previous observations by several telescopes had detected the gaseous material in the ring's central region. But the new view by Hubble's sharp-eyed Wide Field Camera 3 shows the nebula's structure in more detail.
dwarf elliptical galaxies, are also seen in the images above. Messier 32 is the companion immediately south of Andromeda, and Messier 110 is the galaxy located to the northwest (upper right). These small satellite galaxies are both gravitationally-bound to the much larger Andromeda Galaxy.
