The Galactic Center at Different Wavelengths

You are looking at a radio image of the center of the Milky Way galaxy.  Many astronomers believe the bright object in the center is a black hole. For more on the image, see Sagittarius A. To find out what different parts of the electromagnetic spectrum reveal about the galactic center, see The Galactic Center at Different Wavelengths.

To see orbits of stars around the galactic center, check out this Physics to Go feature: UCLA Galactic Center Group.
