Astronomers are obsessed with building larger and larger telescopes. There are two promises that we make with bigger telescopes: that they can see fainter things and that they see more detail. But it's been really hard to follow through on… — Andrea M. Ghez Copy Share Image
Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of the center of black holes doesn't make sense, which is a big clue to physicists that… — Andrea M. Ghez Copy Share Image
The key to proving that there's a black hole is showing that there's a tremendous amount of mass in a very small volume. And… — Andrea M. Ghez Copy Share Image
We have this interesting problem with black holes. What is a black hole? It is a region of space where you have mass that's… — Andrea M. Ghez Copy Share Image

Fortunately, most things around the supermassive black hole are just going to go around it. They're going to orbit it. They don't actually get… — Andrea M. Ghez Copy Share Image
The Keck telescope, which is the largest in the world, had opened just before I began my faculty position at UCLA. — Andrea M. Ghez Copy Share Image
As an astronomer, I get to ignore the details of the things that we dont understand. Theres a lot of work that we can… — Andrea M. Ghez Copy Share Image
One of the key differences between galaxies with super massive black holes is whether or not the black holes are lit up, because they… — Andrea M. Ghez Copy Share Image

Any time things go to infinity in physics, we know we haven't gotten it right. — Andrea M. Ghez Copy Share Image
The star S0-2 orbits around Sgr A* every 16 years and will go through its closest approach in 2018. That's an opportunity to test… — Andrea M. Ghez Copy Share Image
