Research Hubble Spies a Spiral-Snowflake Video

Together with unequal galaxies, spiral galaxies create up approximately 60 percent of the galaxies in the local space. However, despite their prevalence, every spiral galaxy is unique — like snowflakes, no two are alike. This is demonstrated by the arresting face-on spiral galaxy NGC 6814, whose luminous nucleus and spectacular sweeping arms, rippled with an intricate pattern of dark dust, are capture in this NASA/ESA Hubble Space Telescope picture.

NGC 6814 has an very bright nucleus, a telltale sign that the galaxy is a Seyfert galaxy. These galaxies have incredibly active centers that can emit sturdy bursts of radiation. The luminous heart of NGC 6814 is a highly variable source of X-ray energy, causing scientists to suspect that it hosts a supermassive black hole with a mass about 18 million times that of the sun.
As NGC 6814 is a extremely active galaxy, many regions of ionized gas are studded next to its spiral arms. In these large clouds of gas, a burst of star formation has newly taken place, forging the brilliant blue stars that are able to be seen spotted throughout the galaxy.
