Big Hole, Very Deep

Spaceflight now has this summary detailing the most successful attempt to date to measure "the object at the center of our galaxy." Presumed to be a black hole four million times as massive as the sun, it's obscured by huge clouds of dust, making optical observations impossible. By using the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope, they were able to "see through" the dust to perform the observations.
