Lesson Objectives. To appreciate that some galaxies emit far more energy at some wavelengths that can be explained simply in terms of ‘starlight’.. To recall the types of active galaxies.. To show an understanding of the mechanism for producing large quantities of radiation from active galaxies.. Paul . Nulsen. (. CfA. ), Christine Jones (. CfA. ), . William Forman (. CfA. ), Eugene .

When you look into the hazy band of light across the sky, you are actually looking at our galaxy from the inside. While an awesome sight, you can only truly begin to see it if you get away from city lights on a moonless night. . Recap. Canvas homework: due on Wednesday. Lab this week: Galaxy Morphology.
