How Earth's Atmosphere Affects Views of the Sky
2:25:39 - 2:34:07 (08:27)
The Earth's atmosphere affects views of the horizon and the sky, causing distortions and making it necessary for astronomers to adjust their telescopes accordingly. When looking at the horizon, the Earth's atmosphere can cause a half-degree bend, and increasing air mass can also impact views of the sky.

Earth-sized telescopes are actually collecting light with a light bucket, essentially the size of the Earth, which enables us to detect light from very far away.

Summary
Earth-sized telescopes are actually collecting light with a light bucket, essentially the size of the Earth, which enables us to detect light from very far away. The Event Horizon Telescope is different as it combined small telescopes scattered across the Earth to effectively create an Earth-sized angular resolution.

Summary
Deformable mirrors are crucial in correcting the distortion from the Earth's atmosphere in viewing planets and stars. These mirrors consist of thousands of little elements and can manipulate in real-time to achieve better images.
