TRANSCRIPT:
If you look at the Milky Way galaxy, you see this immense collection of a few hundred billion stars. There is an unprepossessing little G-type star on one of the spiral arms called "the sun," and we know there's a whole family of planets and smaller objects around it. We're now beginning to find multiple other solar systems or stellar planetary systems around other stars. The galaxy is filled with these planetary systems and we're just beginning to find and characterize them.
