Scientific paper

Observations of the center of the Galaxy at infrared and radio wavelengths are described. The sources in the region exhibit a complex spatial distribution and several types of motion. The rapid rate of expansion of massive clouds of molecules (hydrogen, carbon monoxide, formaldehyde, hydroxyl radical) suggests that they were expelled from the galactic center by explosive events a few million years ago. High resolution studies of the source Sagittarius A reveal two main sources, the weaker of which has many properties of a supernova remnant. The stronger is believed to contain the dynamical center of the Galaxy. There is evidence of star formation near the galactic center, and very long baseline interferometric studies indicate the presence of a pointlike source emitting at frequencies between 10 to the 9th and 10 to the 14th Hz. It is speculated that this may be a superstar or a black hole.
