When I came back to the US from living in Australia for 4 years, I published a poster with a picture of the moon on in and I placed it “upside down” – someone pointed it out and I looked at the moon and said “the moon is upside down.” This was true – in the Northern Hemisphere – but to people living in the Southern Hemisphere the moon appears “upside down.”
I was shocked, but the claim was true – in the Northern Hemisphere! But to Australians and other people living in places in the Southern Hemisphere the moon appears “upside down.”
Most people, when they look up at the night sky can easily see stars and identify some familiar groups of stars (asterisms and constellations). Some people can even find and name some planets – Venus, Jupiter, and Mars are all bright and easy to see.
But, there are many invisible wonders in the sky – and some of them can be seen without a telescope. In fact they are so big that a telescope is not the right tool to use; we have to use something even more powerful… imagination!
Using visualization and imagination, I am going to show you how to find and “see” a very large structure in our sky: the solar system disk itself.
