Galactic Center
The Galactic Center is the rotational center of the Milky Way galaxy, located approximately 25,000 light-years from Earth in the direction of the constellation Sagittarius. It is a densely populated region containing a supermassive black hole known as Sagittarius A*, surrounded by a high concentration of stars, gas, and dust.

The Galactic Center - A Radio Mystery
28/01/1999
Tuning in to the center of our Milky Way galaxy, radio astronomers explore a complex, mysterious place. A premier high resolution view, this startlingly beautiful picture covers a 4x4 degree region around the galactic center. It was constructed from 1 meter wavelength radio data obtained by telescopes of the Very Large Array near Socorro, New Mexico, USA. The galactic center itself is at the edge of the extremely bright object labeled Sagittarius (Sgr) A, suspected of harboring a million solar mass black hole. Along the galactic plane which runs diagonally through the image are tortured clouds of gas energized by hot stars and round-shaped supernova remnants (SNRs) - hallmarks of a violent and energetic cosmic environment. But perhaps most intriguing are the arcs, threads, and filaments which abound in the scene. Their uncertain origins challenge present theories of the dynamics of the galactic center.
