The Solar Gravitational Lens will Map Exoplanets. Seriously.
Launch Pad Astronomy · 10 recommenders · 9 months
Explains the proposed NASA JPL plan to use the Sun as a gravitational lens, sending solar sail craft to its focal region to image an exoplanet's surface. It covers the distances involved, how imaging with the Sun would work and the mission design.
Why Hacker News readers recommend it: HN strongly recommends it as the clearest, best-illustrated explanation of the solar gravitational lens idea, and links it whenever exoplanet imaging comes up.
