NGC 5204 |
|
This barely spiral galaxy is located about 15 million lightyears away in the constellation Ursa Major. It is an extremely bright X-ray source, which would normally indicate to astronomers that there is a supermassive black hole in the center of the galaxy. However, the X-ray source is slightly offset from the galactic center, which makes the supermassive black hole theory unlikely. At the same time, it is much too luminous in the X-ray region to be the result of a small, stellar-mass black hole. Astronomers are currently studying this galaxy to determine the true cause of this X-ray brightness. |

Equipment 20in RC Optical Systems telescope Operating at f/8.1 Paramount ME Robotic Telescope Mount SBIG ST10XME CCD camera with color filter wheel LRGB color production was used to create this image. Taken during poor seeing. Three iterations of L-R deconvolution (sharpening) algorithm using CCDsharp were applied to the luminance image. Digital Development (DDP) via Maxim/DL was also used in order to display the very dim and very bright details of the image simultaneously. Luminance = 90 minutes binned 1x1 Red = 20 minutes binned 2x2 Green = 20 minutes binned 2x2 Blue = 20 minutes binned 2x2 Minimum credit line: Doug Matthews/Adam Block/NOAO/AURA/NSF
