galaxy NGC 6872 is 522,000 light-years across
(NASA) – On Jan. 10, 2013, a composite image of the giant barred spiral galaxy NGC 6872 combines visible light images from the European Southern Observatory’s Very Large Telescope with far-ultraviolet data from NASA’s Galaxy Evolution Explorer and infrared data acquired by NASA’s Spitzer Space Telescope.
NGC 6872 is 522,000 light-years across.
This makes it more than five times the size of the Milky Way galaxy; in 2013, astronomers from the United States, Chile, and Brazil found it to be the largest-known spiral galaxy, based on archival data from GALEX.
