A Solar Gravitational Lens Will be Humanity's Most Powerful Telescope. What are its Best Targets?
One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed by objects closer to us. Under the right conditions, gravitational lensing can act as a kind of natural telescope, brightening and magnifying the light of distant objects. Astronomers have used this trick to observe some of the most distant galaxies in the universe. But astronomers have also thought about using this effect a little closer to home.

NASA had Been Designing Lunar Bases for Decades Before Armstrong First Set Foot on the Moon
It’s only natural to look at the Moon and wonder what it would be like to live there. Thanks to Buzz Aldrin who landed there in 1969, we know it’s a magnificent desolation. Even before the Apollo missions science fiction writers and scientists knew how desolate the place was. But, as far back as the late 19th Century, they also saw it as a natural outpost. So did NASA, the former Soviet Union, and their respective militaries. And, that led to people on both sides drawing up elaborate plans for Moon bases.
