An evening with John McEvoy, discussing the structure of The Milky Way

Background information about our galaxy, The Milky Way.

• We’re going to go over the structure and size of the Milky Way as a whole, and our place in it.

• We’ll examine the galactic centre and the supermassive black hole.

• We’ll explore the galactic disc with its spiral arms, and cover the latest information on the galactic halo.

• We’ll explain how we come to know these things from deep within the galaxy itself.
