How to make a telescope out of the sun
A trick of physics could help us find alien life. But while JWST will give us tons of information
about these celestial bodies, there’s something that it can’t do: take a high-resolution image of an earth-like exoplanet — specifically, an image where we can clearly see evidence of possible life on another world, such as land masses, clouds, and bodies of water.This method would use a phenomenon called gravitational lensing to capture that kind of an image.occurs when the gravity of a massive object, like a galaxy or star, bends the space-time around it.
Turyshev’s proposed solar gravitational lens would use the sun as that massive object, magnifying the light of a distant exoplanet in order to construct a high-resolution image we otherwise couldn’t visualize. We sat down with Turyshev to talk about what it would take to reach this goal and how he hopes to achieve it within just a few decades. Watch our video above to see more.
