The current precision of the Doppler shifts in the absorption lines in stellar spectra is ~3 km s-1. Show that it would not be possible to detect the presence of the Earth from a distant solar system using the Doppler method. State one method that might allow the Earth to be detected. (The Earth's mass is 1/333 000 that of the Sun. 1 AU = 1.49× 10' m.)

One important goal of astronomers is to have a telescope inspace that can resolve planets like the earth orbiting other stars. If aplanet orbits its star at a distance of 1.5 * 10^11 m (the radius of theearth’s orbit around the sun) and the telescope has a mirror of diameter8.0 m, how far from the telescope could the star and its planet be if thewavelength used was (a) 690 nm and (b) 1400 nm? Use the Rayleighcriterion and give your answers in light-years (1 ly = 9.46 * 1015 m).

The difference in absolute magnitude between two objects at the same distance is related to their fluxes by the flux-magnitude relation. FA FB = 2.51(MB − MA) A distant galaxy contains a type I classical Cepheid whose period results in an absolute magnitude estimate of −6.3. If this star were placed next to our Sun (M = +4.8) and you observed them both from the same distance, how much more flux would the Cepheid emit than the Sun? FCepheid FSun = If a galaxy contains a supernova that at its brightest has an apparent magnitude of +11, how far away is the galaxy? Assume that the absolute magnitude of the supernova is −18. Hint: Use the magnitude-distance formula: d = 10(mV − MV + 5)/5 . The hydrogen Balmer line H? has a wavelength of 486.1 nm. It is shifted to 559.7 nm in a quasar's spectrum.
