NASA's upcoming Nancy Grace Roman Space Telescope will feature the first space-based active coronagraph, designed to block starlight and enable the imaging of exoplanets similar to those in our solar system. This advanced instrument utilizes two deformable mirrors with thousands of actuators to precisely sculpt the mirror surfaces, canceling out unwanted light and glare. The telescope's capabilities, including a wide-field camera significantly larger than Hubble's, will also aid in studying dark matter and dark energy, and detecting an estimated 100,000 new exoplanets.
