Webba) Optical reflectors can have their detector placed at the prime focus, whereas radio telescopes never do. In astronomy, an interferometer can be used to: a) speed up the processing of CCD images. b) yield better seeing conditions with optical telescopes. c) improve the angular resolution of radio telescopes. Webb8 dec. 2024 · The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has captured an image of a planet orbiting b Centauri, a two-star system that can be seen with the naked eye. This is the hottest and most massive planet-hosting star system found to date, and the planet was spotted orbiting it at 100 times the distance Jupiter orbits the …

Their light gets smeared across a seeing disc a few arcseconds in diameter. Planets, with an angular diameter of ~10-30 arcseconds are extended sources and thus less affected. iccnashuanh.org virtual massWebb12 maj 2024 · Acquiring a good image of a large object that appears tiny when viewed from Earth requires a telescope with extraordinarily fine resolution, or the ability to detect the smallest possible details in an image.
