The Nearest Galaxies

What is the most remote object ever visible with the naked eye? The answer is: the Great Spiral in Andromeda, which is a member of our Local Group of galaxies, but is still very remote - its light takes over two million years to reach us. The Local Group is now known to contain over 25 members, some of which are huge systems while others are dwarf galaxies. Patrick Moore talks about the Local Group to Heather Couper , lecturer at the Caird Planetarium, Greenwich.
