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 sucked in. — 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 Einstein's General Relativity theory through very precise measurements of this star's short period orbit. — 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

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
Black holes are very exotic objects. Technically, a black hole puts a huge amount of mass inside of zero volume. So our understanding of… — 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
