Which of the following techniques has resulted in the BEST angular resolution of the image?
A) adaptive optics as used with Keck II on Mauna Kea
B) HST, an orbiting telescope
C) active optics, as used with the New Technology Telescope in Chile
D) interferometry, as used with the four telescopes of the VLT at the Paranel facility in Chile

Question

Quizplus · Accepted Answer

HST, an orbiting telescope, has resulted in the best angular resolution of the image due to its location above Earth's atmosphere, which reduces atmospheric turbulence and distortion of the image. This allows for a much clearer and sharper image than ground-based telescopes using adaptive optics, active optics, or interferometry.
