Center of the Galaxy

Radio and infrarred observations allow astronomers to observe the center of the Galaxy.

Here is a wide angle infrared view that shows the central bulge. (It if from the COBE satellite.)

We can see into the very center of the Galaxy (in the constellation Sagittarius) with infrared and radio telescopes. The results are discussed in Sec. 25-7 of our book, which includes nice pictures.

The main result is that there is a strong radio source called Sagittarius A* at the center of the Galaxy.
