摘要：

The remarkable optical properties of the solar gravitational lens (SGL) include major brightness amplification (similar to 10(11) on the optical axis, at a wavelength of 1 mu m) and extreme angular resolution (similar to 10(-10) arcsec). A deep space mission equipped with a modest telescope and coronagraph, traveling to the focal area of the SGL that begins at similar to 548 astronomical units (AU) from the Sun, offers an opportunity for direct megapixel imaging and high-resolution spectroscopy of a habitable Earth-like exoplanet. We present a basic overview of this intriguing opportunity.
