It's like trying to pick out an individual inside the middle of a busy city, with lights and cars, and things happening all around them.
But that wasn't the only problem. Vast, swirling 1 clouds of dust and gas prevent visible light from the centre of our galaxy 2 from reaching us, making what lies beyond hidden from view.
It's like putting a blanket over the thing you are trying to look at. It's putting a thick fog around that. So there is only certain wavelengths 3 of light that can penetrate 4 through that.
Without the means to see through that dust, the black hole that theory suggests it should reside at the centre of our Milky 5 Way would remain nothing more than a bold but unproven idea.
With the quest to find the black hole seemingly blocked, there was nevertheless one glimmer 6 of hope. Now at least astronomers 7 had some sort of notion where one should be hiding. To tackle the problem, what would be needed was a new generation of telescopes and that would take a new generation of astronomers.
We were just at the point where we had the technology to address that question. And so in some sense it was I had the right hammer and I was looking for the right nail.
With her Los Angeles group, Andrea Ghez began work on a telescope that could see through to the hidden centre of our galaxy.
