An enormous arc of hot gas protruding from the center of our galaxy has been discovered by astronomers near the center of the Milky Way. The existence of the arc could mean that stars are not being formed there at the high rate previously assumed. This assumption had been made because of the intense radio emissions rising there.
Discovered using the National Radio Astronomy Observatory's Very Large Array (VLA) in New Mexico, the structure resembles a solar prominence, which is a great streamer or column of glowing gas that often rises to great heights at enormous velocities about the sun's surface. The arc is 150 light years long and 30,000 light years from the earth.
