It was a stunning 1 discovery. After a quest lasting 2 decade, Donald Lynden-Bell had been proved right. Here indeed, just where he had predicted, was a super massive black hole. But in the last year, the quest to find and understand black holes has suddenly become even more exciting. That's because out there in space, something is about to happen that really is going to drag black holes out of the shadows, to reveal them as they really are.
The reason for the excitement is all because of a discovery made in Munich. Here a group working with the European Space Observatory 3 had shed credit for discovering the black hole at the heart of the Milky 4 Way. In late 2011, they made an almost accidental discovery, a discovery that's triggered this year's rush of excitement. It was while reviewing some data which had previously 5 been dismissed as second rate that they noticed something unusual.
We decided 6 in 2011 we should look at our data which is B-rated so to say data, which is of somewhat lower quality because the resolution is not as good as it would get under the best weather conditions. And then boom, there was all of a sudden one source which was very close to the black hole.
