This Cosmic Video was produced from the May 28, 2014 Astronomy Talk given at Kahilu Theatre. The original description is below:
The Galactic Center Group at UCLA has used the W. M. Keck Observatory for the past two decades to observe the center of the Milky Way at the highest angular resolution possible. This work established the existence of a supermassive black hole at the heart of our Galaxy. In this talk, Dr. Leo Meyer, Research Scientist for the UCLA Galactic Center Group, will focus on the black hole itself and the gas that it swallows. The feeding of the black hole is a turbulent process resulting in highly variable emission of infrared light. Observations of this variability provide a great way to learn about the black hole and its immediate environment.
