Suppose you send a probe to land on Mercury, and the probe transmits radio signals to Earth at a wavelength of 59.0000 cm. You listen for the probe when Mercury is moving away from Earth at its full orbital velocity of 48 km/s around the sun. What wavelength (in cm) would you have to tune your radio telescope to detect the signal? (Hint: Use the Doppler shift formula .) (Note: the speed of light if 3.0 x 10^5 km/s. Give your answer to at least four decimal places.)

You are an astronomer and are searching for planets in other stellar systems for which conditions on the surface of the planets are similar to the Earth. You have identified a candidate star, Tycho1601 that you know has same size to the Sun but 1.4 times the surface temperature of the Sun (our Sun). Around that star there are four planetsrotating around it. You are about to invest valuable telescope time in studying the individual planets which one you start with?A) Planet TychoA located at a distance that is half the distance between our Earth and our Sun.B) Planet TychoB located at a distance that is equal to the distance between our Earth and our Sun.C) Planet TychoC located at a distance that is double the distance between our Earthand our Sun.D) Planet TychoD located at a distance that is ten times the distance between our Earth and our Sun.
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.
