This is a fantastic image directly from NASA’s archives and shows the wonders of the universe.
Note that some of the NASA spaces images have some slight blurring due to the subject, this is natural. You have your choice of size and finish for the photo. The size you choose may require cropping and the finished image may appear slightly different than the one shown. If preferred a white border can be added above/below or left/right to allow all of the original image to print. Unless requested when placing your order, your image may be cropped. If you would like to see how a specific image will look for the size you have chosen, please contact us and indicate the size you are interested in.

Matte Finish:
E-Surface Photo Paper is by far our most popular photographic paper. As a professional paper, it boasts rich, sharp color that won't fade or yellow, creating beautiful prints that will last for years to come.
Glossy (Metallic) finish:
Our Metallic Photo Paper features a unique pearlescent surface. It offers highly saturated colors, ultra-bright backgrounds, and will last a lifetime with typical home storage.
NGC 3627: Revealing Hidden Black Holes
The spiral galaxy NGC 3627 is located about 30 million light years from Earth. This composite image includes X-ray data from NASA's Chandra X-ray Observatory (blue), infrared data from the Spitzer Space Telescope (red), and optical data from the Hubble Space Telescope and the Very Large Telescope (yellow). The inset shows the central region, which contains a bright X-ray source that is likely powered by material falling onto a supermassive black hole.
A search using archival data from previous Chandra observations of a sample of 62 nearby galaxies has shown that 37 of the galaxies, including NGC 3627, contain X-ray sources in their centers. Most of these sources are likely powered by central supermassive black holes. The survey, which also used data from the Spitzer Infrared Nearby Galaxy Survey, found that seven of the 37 sources are new supermassive black hole candidates.
Confirming previous Chandra results, this study finds the fraction of galaxies found to be hosting supermassive black holes is much higher than found with optical searches. This shows the ability of X-ray observations to find black holes in galaxies where relatively low-level black hole activity has either been hidden by obscuring material or washed out by the bright optical light of the galaxy.
The combined X-ray and infrared data suggest that the nuclear activity in a galaxy is not necessarily related to the amount of star-formation in the galaxy, contrary to some early claims. In contrast, these new results suggest that the mass of the supermassive black hole and the rate at which the black hole accretes matter are both greater for galaxies with greater total masses.
