The center of our galaxy harbors highly energetic phenomena.
Infrared observations indicate stars near the center of our galaxy are packed close together.
Radio observations indicate presence of a black hole with a mass roughly equal to 2 million times the mass of the Sun. The center of our galaxy harbors highly energetic phenomena. The center of our galaxy is 8500 parsecs away, in the direction of the constellation Sagittarius. In these lectures, I'll be considering mainly the region within 100 parsecs of the galactic center. The center of our galaxy can't be seen at visible wavelengths.
