- 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.)The angular size of the black hole at the center of M87 is about 10microarcseconds, or 2.8 x 10-9 degrees. Ignoring atmospheric seeing, whatwould be the diameter (in meters) required for a single telescope to resolve an image of this black hole in the near-infrared (wavelength = 1 micrometer)?How long does it take light from the sun 93 million miles away to the earth
- Use Wien's Law to calculate the peak wavelength of light coming from the Sun. Assume T=5800 K for the surface temperature of the Sun. Wein's displacement law says that the blackbody temperature and peak wavelength multiplied together give a constant of 0.29 cm-K. (K is degrees Kelvin).The 305-m diameter Arecibo radio telescope (located in Puerto Rico) is shown below, prior to its unfortunate recent collapse. Approximately how close on the sky could two radio stars be located while still being distinguishable as separate stars by Arecibo? Assume radio waves of frequency 1420 MHz (the famous atomic hydrogen line). 17 arcsec 17 arcmin 29 arcmin 2.9 arcmin 17,000 arcsecUsing this equation Wein's Law: What is the wavelength of maximum intensity and the total energy emitted by a celestial object at absolute zero?
