PODCAST 1: Star Mapping

 

When we say we can see the Milky Way, we are really talking about looking toward the center of our galaxy where the stars, dust, and gasses are most dense. However, every star we see in the night sky with our bare eyes is part of the Milky Way. (We need a telescope to see more distant stars, although we can see some other galaxies as smudges of light.) Think of it as if you’re looking toward downtown when standing on the beautiful beaches of Lake Erie. Everything you see around you is part of the Cleveland area, but when you look toward downtown the lights and the buildings are brighter and more closely packed together.
