The REAL Possibility of Mapping Alien Planets!

Season 8 Episode 29 | 14m 59s | Video has closed captioning.

This is the craziest proposal for an astrophysics mission that has a good chance of actually happening. A train of spacecraft sailing the sun’s light to a magical point out there in space where the Sun’s own gravity turns it into a gigantic lens. What could such a solar-system-sized telescope do? Pretty much anything. But definitely map the surfaces of alien worlds.
