When astronomers discuss the apertures of their telescopes, they say bigger is better. Explain why.
a) A wider aperture can observe a significantly larger portion of the sky. b) A wider aperture makes a telescope easier to aim. c) A wider aperture allows a telescope to collect more light, so it can produce images with higher resolution. d) A wider aperture allows a telescope to collect more light, so it can detect fainter light sources.
The Giant Magellan Telescope is a new telescope being built in Chile with a mirror 25 meters in diameter.
Part 1: If you neglect the impact of Earth's atmosphere, what is the angular resolution limit (diffraction limit or resolving power) of this telescope in green light (500 nm)?
Give your answer in arcseconds.
Part 2: The current Magellan telescope has a mirror 6 meters in diameter. How much more light per second will the Giant Magellan capture compared to the current
Magellan?

- How does the resolving power of the Mount Palomar 5-m telescope compare with that of the 2.4-m Hubble Space Telescope? AMount Palomar dHubble Space Telescope Why does HST generally still outperform the ground-based 5-m telescope? The resolving power of the Mount Palomar 5-m telescope has a higher value than that of HST, and telescopes with higher values for resolving power can not distinguish objects as well as telescopes with lower values for resolving power. Earth's atmosphere affects visibility for the Mount Palomar 5-m telescope and limits resolving power to about 0.5 seconds of arc. HST is not affected by distortion due to the atmosphere. The resolving power of the Mount Palomar 5-m telescope has a lower value than that of HST, and telescopes with lower values for resolving power can not distinguish objects as well as telescopes with higher values for resolving power. HST is in orbit around the Earth, and so it is closer to the stars than the Mount Palomar 5-m telescope.
