High resolution: The telescope will need to be able to resolve small details on the surface of planets, such as the presence of vegetation or other signs of life. This will require a large aperture and a high angular resolution.
Wide field of view: The telescope will need to be able to survey a large area of the sky to increase the chances of finding planets that could support life. This will require a large field of view.
Sensitivity: The telescope will need to be able to detect faint signals from distant planets. This will require a high sensitivity and a low noise level.
Spectral resolution: The telescope will need to be able to measure the spectrum of light from planets to identify the presence of certain gases, such as oxygen and methane, which could be indicators of life. This will require a high spectral resolution.
Polarimetric imaging: The telescope will need to be able to measure the polarization of light from planets to detect the presence of certain types of particles, such as dust or ice, which could also be indicators of life. This will require a high polarization sensitivity.
In addition to these technical requirements, the next generation telescope will also need to be located in a very dark and remote location to avoid interference from light pollution and other sources of noise.
