Some 55 million light-years distant, the galaxy extends for over 100,000 light-years, seen within the boundaries of the southern constellation Lupus. Its inner 40,000 light-years are shown in sharp detail in this composite of Hubble Space Telescope image data. The bright compact core of NGC 5643 is also known as a strong emitter of radio waves and X-rays. In fact, NGC 5643 is one of the closest examples of the Seyfert class of active galaxies, where vast amounts of dust and gas are thought to be falling into a central massive black hole.
