2. Angular resolution - Wikipedia

   en.wikipedia.org/wiki/Angular_resolution

   The highest angular resolutions for telescopes can be achieved by arrays of telescopes called astronomical interferometers: These instruments can achieve angular resolutions of 0.001 arcsecond at optical wavelengths, and much higher resolutions at x-ray wavelengths.

3. List of largest optical reflecting telescopes - Wikipedia

   en.wikipedia.org/wiki/List_of_largest_optical...

   This list of the largest optical reflecting telescopes with objective diameters of 3.0 metres (120 in) or greater is sorted by aperture, which is a measure of the light-gathering power and resolution of a reflecting telescope. The mirrors themselves can be larger than the aperture, and some telescopes may use aperture synthesis through ...

   The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun, observed from Earth, stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.

   Those telescopes have for years zoomed in on the far corners of the known universe, unveiling planets, stars and galaxies in high resolution. The James Webb Space Telescope, which launched in 2021 ...

6. List of radio telescopes - Wikipedia

   en.wikipedia.org/wiki/List_of_radio_telescopes

   A wide-band radio telescope instrument consists of two parabolic cylinders 1 km long and 40 m width. One cylinder extend from east to west and the 2nd from north to south. DKR-1000 has a high sensitivity and the telescope allows simultaneous observations at any wavelengths in the range from 2.5m to 10m.

7. Very Large Telescope - Wikipedia
