Chapter 35, Problem 47EAP
Alpha Centauri, the nearest star to our solar system, is 4.3 light years away. Assume chat Alpha Centauri has a planet with an advanced civilization. Professor Dhg, at the planet’s Astronomical Institute, wants to build a telescope with which he can find out whether any planets are orbiting our sun.
a. What is the minimum diameter for an objective lens that will just barely resolve Jupiter and the sun? The radius of Jupiter’s orbit is 780 million km. Assume ? = 600 nm.
b. Building a telescope of the necessary size does not appear to be a major problem. What practical difficulties might prevent Professor Dhg’s experiment from succeeding?

Sometime around 2022, astronomers at the European Southern Observatory hope to begin using the E-ELT(European Extremely Large Telescope), which is planned to have a primary mirror 42 m in diameter. Let us assume that the light it focuses has a wavelength of 550 nm. (1 light-year = 9.461×10^15 m)
Note: Jupiter's Diameter dj=1.43×10^8 m
1)What is the most distant Jupiter-sized planet the telescope could resolve, assuming it operates at the diffraction limit? (Express your answer to two significant figures.)
2)What is the most distant Jupiter-sized planet the telescope could resolve, assuming it operates at the diffraction limit? (Express your answer to two significant figures.)
3)The nearest known exoplanets (planets beyond the solar system) are around 20 light-years away. What would have to be the minimum diameter of an optical telescope to resolve a Jupiter-sized planet at that distance using light of wavelength 550 nm? (Express your answer to two significant figures.)

There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forward
- i need the answersarrow_forwardTutorial You want to resolve 9.5 m features on Mercury with a 2 m telescope using 550 nm light. How close (in km) do you need to be? How does the orbital velocity (in km/s) at this altitude on Mercury compare to the orbital velocity at this altitude on Earth? (MẸ = 5.97 x 1024 kg, Re = 6.38 x 10 km, M = 3.30 x 1023 kg, R = 2440 km.) Part 1 of 4 The small angle formula tells us how distance and linear size are related to the angular size of an object. 2.06 x 105 D And the diameter of a telescope is related to the resolving power by: a- 2.06 x 105 diameter Part 2 of 4 First we should determine the resolving power of our 2 m telescope. a = 2.06 x 10 What is the wavelength you are trying to observe at? m diameter arc secondsarrow_forwardThe planet Mercury is closer to the Sun than the Earth is, so it can sometimes come between Earth and Sun. That's called a transit. A transit is like a failed solar eclipse: In a solar eclipse, the Moon gets between Earth and Sun and blocks all sunlight. In a transit, Mercury blocks only a small fraction of the Sun's light because Mercury isn't close enough to us to completely block our view of the Sun. We want to calculate by how much the Sun will be dimmed when such a transit occurs, because that's important to know for satellites which are powered by solar panels (shown hovering around the Earth in the image above). Without Mercury in the way, the radiation intensity that hits the top of the Earth's atmosphere from the Sun is 1,360.8 W/m2 (W stands for Watt, measuring energy transferred per second). The fraction of this intensity that is blocked by Mercury during a transit is equal to the ratio between the cross-sectional area of Mercury (as seen from Earth) and the…arrow_forward

- Which of the following statements are true? Choose all that apply. If light from a star passes through an exoplanet's atmosphere, we can look at the absorption spectra to determine what elements & compounds are in the atmosphere. For a telescope, increasing fe will decrease the actual size of the image seen by the person looking through the telescope. In crown glass, the index of refraction for red light is 1.512 and for orange light it is 1.514. Thus in crown glass, red light is faster than orange light. If unpolarized light is incident on a polarizer, 50% will pass through. The glasses for nearsighted people create real images for them to see. The smaller the diameter of an optic is, the larger the minimum angle it can discern is.arrow_forwardYou 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 usarrow_forwardThe planet Uranus was discovered in 1781, and Neptune, the next planet outward from the Sun, was discovered in 1846. Imagine you're an astronomer in 1846, and you start wondering if there's another planet out beyond Neptune. You decide to try and discover its existence using the same method that was used for Neptune. How will you do this? Group of answer choices You'll recruit a large number of astronomers to use their telescopes to carefully scan the sky in directions that are far from the ecliptic. The regions around the north and south celestial poles will probably be the best "hunting grounds" for the new planet. You'll examine Uranus and Neptune very carefully, on every clear night, for several years, to see if you can find any evidence that sunlight has been reflected off of the `new' planet, then off of Uranus or Neptune, before arriving on Earth. On rare occasions when Neptune passes in front of the Sun, as seen from Earth, you'll look carefully at the Sun (with a safe…arrow_forward
