The documentary starts with an imaginary disaster: Venus hitting the Earth and destroying both. A fantasy? Perhaps, but many astronomers, scientists and other experts believe that if the Moon didn't exist that would have happened already. With the help of some of these scientists, the documentary explores the benefits to our planet of its sole satellite by speculating on what Earth would have been like if it had not been there.

Can we now start believing in the good opportunities that await us,

A very educational, interesting and perfect presentation. I enjoyed all aspects of this program and it has inspired me to learn more about astronomy. Thank-you so much for this wonderful "learning program" of astronomy.

It has inspired my daughter, Rachel, to do further research on this matter. She has always maintained that there is a way to explore our galaxies.

It was disappointing not to view more information on this aspect on your web-site. However, we remain the faithful explorer.
