How do we learn about the conditions at the center of our own galaxy, the Milky Way?
A) High-resolution photographs obtained by the Hubble Space Telescope have revealed the galactic center using visible light.
B) While we cannot see the galactic center with visible or ultraviolet light, radio and X-rays from the center can be detected and used to determine the conditions there.
C) The gas and dust in the Milky Way prevent any type of direct observation of the galactic center, but theoretical models allow us to predict what is happening there.
D) We must look at the centers of other (external) galaxies and assume that they are similar to the Milky Way.
