Infrared Detection of The Supermassive Black Hole

The first detection of infrared (3.8 micron) light from plasma falling onto the supermassive black hole at the center of the Milky Way galaxy. The location of the black hole is marked with an arrow. The brightness variations, which occur on timescales as short as 40 minutes, reveal that the plasma is much more energetic than previously believed, showing that violent events occur almost continually.
