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?

- Why can’t we use visible light telescopes to study molecular clouds where stars and planets form? Why do infrared or radio telescopes work better?arrow_forwardDescribe the techniques radio astronomers use to obtain a resolution comparable to what astronomers working with visible light can achieve.arrow_forwardThe HST cost about $1.7 billion for construction and $300 million for its shuttle launch, and it costs $250 million per year to operate. If the telescope lasts for 20 years, what is the total cost per year? Per day? If the telescope can be used just 30% of the time for actual observations, what is the cost per hour and per minute for the astronomer’s observing time on this instrument? What is the cost per person in the United States? Was your investment in the Hubble Space telescope worth it?arrow_forward

- You are the leader of the international Event Horizon Telescope, a collaboration of radio astronomers who want to take a picture of the black hole at the center of the Milky Way (Sag. A*). That black hole has a mass of about 4.1 million solar masses and is about 8 kpc away. If you are observing with a radio wavelength of about 1 mm, what effective diameter of your radio interferometric array is needed in order to just resolve the diameter of the Sag. A* black hole event horizon. (Assume the black hole is non-spinning, so its diameter is twice the event horizon radius.) Express your answer as a multiple of the Earth's radius. [Hint: you will need to recall and combine three formulas introduced throughout this course, including one about how big a black hole is, one about the criterion for resolving objects, and another that relates distance, sizes, and angles.] There really is an Event Horizon Telescope, and they are responsible for the first image of a black hole in the galaxy M87…arrow_forwardWhat are the arguments for building the TMT telescope?arrow_forwardLet’s say that we have a radio dish that is 22 meters in diameter. It is designed to detect radio waves at 0.00006 centimeters in wavelength. What is the maximum resolution, or diffraction limit, of this telescope in arcseconds?

- The Mars Reconnaissance Orbiter (MRO) flies at an average altitude of 280km above the Martian Surface. If its cameras have an angular resolution of 0.2 arc seconds, what is the size of the smallest objects that the MRO can detect on the Martian surface? Use the equation: S =x × d / 206265 arcseconds / radian , where S is the true size of the object, d is the distance from the detector to the object, and x is the angular size of the object. Your answer will be in km (you can ignore the radians unit (it should appear, but the equation made a simplifying assumption that dropped it out.arrow_forwardThe James Webb Space Telescope has a primary mirror of diameter ? = 6.5metres.
