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, swirling1 clouds of dust and gas prevent visible light from the centre of our galaxy2 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 wavelengths3 of light that can penetrate4 through that.
Without the means to see through that dust, the black hole that theory suggests it should reside at the centre of our Milky5 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 glimmer6 of hope. Now at least astronomers7 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.
