The Supermassive Black Hole

Enjoy this rebroadcast of a rare observing run at the W. M. Keck Observatory, home of the two largest and most scientifically productive telescopes on Earth.On the evening of July 3, 2014, both of the mighty 10-meter Keck Observatory telescopes were steered by Dr. Andrea Ghez and her team of observers from the UCLA Galactic Center Group to study the supermassive black hole at the center of our galaxy. They studied an enigmatic object named G2, set up tests for Einstein’s General Relativity and gathered more data on what they describe as The Paradox of Youth: objects unexpectedly developing around the black hole.NOTE: The audio improves dramatically at about 10 minutes.
