What technology do future Extremely Large Telescopes use to improve resolution?
Answer
Advanced adaptive optics
Ground-based observatories under construction, known as Extremely Large Telescopes (ELTs), are designed to overcome current resolution limits through the use of advanced adaptive optics. These systems use flexible mirrors that adjust rapidly to counteract the turbulence caused by the Earth's atmosphere, which otherwise distorts incoming light. By canceling out this atmospheric interference, these telescopes can achieve a level of clarity and angular resolution that is significantly higher than previous ground-based instruments.
