Forget man on the moon - telescope on the moon

That is exactly what scientists are proposing, an enormous liquid-mirror telescope on the moon that would be even more precise than the current Hubble Space Telescope. It's a very interesting article that goes into detail as to the cost and the science involved in getting the design to a stage where it is actually possible. Granted, it's estimated to cost 4.5 billion dollars but considering the potential for learning more about our galaxy and those beyond? The benefits could be very rewarding.
