详解 NASA JPL 提出的宏大构想：将太阳本身作为引力透镜，发射太阳帆探测器飞赴引力透镜焦点区域，对数百光年外的系外行星地表进行百公里级分辨率成像。涵盖极端星际距离、成像物理机制与探测任务设计。
为什么 HN 推它
HN 极力推荐的硬科幻级科普视频，配图与可视化水准极高，每当论坛探讨系外行星探索方案时必会被翻出来分享。
「特效渲染与可视化动画做得太棒了，解说也是由浅入深，非常容易理解。」HN 网友原话：It's got some great graphics and visualisations, and is accessibly narrated.
英文原摘要（HackerTube / Claude 整理）
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.
HN strongly recommends it as the clearest, best-illustrated explanation of the solar gravitational lens idea, and links it whenever exoplanet imaging comes up.
HN 上的提及
A recent video talking about what it could take to get high resolution imagery of exoplanets.
is a great great video on the subject. I can't recommend enough
yes, can't recommend this enough!
Cited as a great future space project.
I heard about this fascinating idea of using the gravitational lensing of our own sun to image the surface of exoplanets
