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?
You record the spectrum of a distant star using a telescope on the ground on Earth. Upon
analysing the spectrum, you discover absorption lines spaced at intervals typical of oxygen
atoms. Which of the following are possible interpretations of this evidence? Select all that
apply.
The width of the spectral lines gives the diameter of the star
The star is likely orbited by habitable planets with breathable atmospheres.
The height of the spectral lines above the star's general blackbody spectral curve tells us how much
oxygen is in the star
The atmosphere of Earth contains oxygen
The red or blueshift of the set of lines can tell us the speed of the star's motion toward or away from us
Remote Spectroscopy. Spectrometers mounted on aircraft and satellites have been used to obtain spectralinformation about the earth. How do these systems work? Cite specific uses of these remote spectroscopytechniques.

- Describe the techniques radio astronomers use to obtain a resolution comparable to what astronomers working with visible light can achieve.arrow_forwardThe Weather Monitor. Your South American expedition splits into two groups: one that stays at home base, and yours that goes off to set up a sensor that will monitor precipitation, temperature, and sunlight through the upcoming winter. The sensor must link up to a central communications system at base camp that simultaneously uploads the data from numerous sensors to a satellite. In order to set up and calibrate the sensor, you will have to communicate with base camp to give them specific location information. Unfortunately, the group's communication and navigation equipment has dwindled to walkie-talkies and a compass due to a river-raft mishap, which means your group must not exceed the range of the walkie-talkies (3.0 miles). However, you do have a laser rangefinder to help you measure distances as you navigate with the compass. After a few hours of hiking, you find the perfect plateau on which to mount the sensor.

Group of answer choices It consists of frequencies which are greater than the frequencies of atmospheric emissions. It relates to the natural frequencies of vibration of hydroxyl (OH) and hydrogen (H), respectively. It occurs in that part of the electromagnetic spectrum where the galactic "noise" from stars and interstellar clouds is minimized. It is considered the "electromagnetic oasis" for interstellar communication. It corresponds to wavelengths in the 18-21 cm range.arrow_forward
