The luminous heart of NGC 6814 is a highly variable source of X-ray radiation, causing scientists to suspect that it hosts a supermassive black hole with a mass about 18 million times that of the sun.Īs NGC 6814 is a very active galaxy, many regions of ionized gas are studded along its spiral arms.
These galaxies have very active centers that can emit strong bursts of radiation. NGC 6814 has an extremely bright nucleus, a telltale sign that the galaxy is a Seyfert galaxy. This is demonstrated by the striking face-on spiral galaxy NGC 6814, whose luminous nucleus and spectacular sweeping arms, rippled with an intricate pattern of dark dust, are captured in this NASA/ESA Hubble Space Telescope image. However, despite their prevalence, each spiral galaxy is unique - like snowflakes, no two are alike. Together with irregular galaxies, spiral galaxies make up approximately 60 percent of the galaxies in the local universe.
