"From the Ted Talk by Andrea Ghez: The hunt for a supermassive black hole"

Unscramble the Blue Letters

Now, what I want to talk about are the supermassive black holes. And the srsmpiseavue black holes are thought to reside at the center of galaxies. And this beautiful picture taken with the Hubble Space Telescope shows you that gaaelixs come in all shapes and szeis. There are big ones. There are little ones. Almost every ojbect in that picture there is a galaxy. And there is a very nice spiral up in the upper left. And there are a hundred billion stars in that gxlaay, just to give you a sense of scale. And all the light that we see from a taiycpl galaxy, which is the kind of galaxies that we're seeing here, comes from the light from the stars. So, we see the galaxy because of the star lhigt.

And all the light that we see from a typical galaxy, which is the kind of galaxies that we're seeing here, comes from the light from the stars. So, we see the galaxy because of the star light.
