The center of our galaxy can't be seen at visible wavelengths. The image immediately below is a photograph at visible wavelengths of an area 20 degrees by 40 degrees centered upon the galactic center. As you can tell, there's a lot of dust between us and the center of the galaxy. In the infrared photo, the dimming by dust is much less, and we can see that the center of the galaxy is actually quite bright. Astronomers still don't know what's going on here, exactly.
Infrared observations indicate that stars near the center of our galaxy are packed close together.
Infrared light at a wavelength of about 2000 nanometers is emitted by cool stars near the galactic center and is not strongly affected by dust. Observations at infrared wavelengths indicate that the number of stars increases rapidly as you approach the galactic center. Within a parsec or so of the center, the density of stars is 10 million stars per cubic parsec. To put this number in perspective, the density of stars in the Sun's neighborhood is only 0.2 stars per cubic parsec. If the star Sirius were only 1000 A.U. from the Sun, it would be twelve times brighter than the full moon.
