Overview

最終更新: 2026年6月8日

The Solar Gravity Lens (SGL) is a theoretical application of general relativity where the Sun's gravity acts as a lens, focusing light from distant stars or planets to a focal region starting at approximately 550 AU from the Sun. This effect could potentially allow for high-resolution imaging of exoplanets, providing detail that would otherwise require a telescope the size of a planet.
