You record the spectrum of a distant star using a telescope on the ground on Earth. Uponanalysing the spectrum, you discover absorption lines spaced at intervals typical of oxygenatoms. Which of the following are possible interpretations of this evidence? Select all thatapply.The width of the spectral lines gives the diameter of the starThe 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 muchoxygen is in the starThe atmosphere of Earth contains oxygenThe red or blueshift of the set of lines can tell us the speed of the star's motion toward or away from us

Radio astronomy involves wavelengths much longer than those of visible light, and many orbiting observatories have probed the universe for radiation of very short wavelengths. What sorts of objects and physical conditions would you expect to be associated with emission of radiation at very long and very short wavelengths? (Select all that apply.) very long wavelengths cold cold gas cosmic background radiation nuclear reactions ++ Opulsars solar corona very high-energy processes very short wavelengths cold gas cosmic background radiation nuclear reactions pulsars solar corona very high-energy processes
Imagine that in the future, scientists plan on colonizing planets that orbit other stars. Based on your knowledge of the life cycle of stars, decide which type of star (High mass or Low mass) the planet should orbit that would allow for human life to safely live on that planet for the longest period of time. Explain your answer using examples from the life cycle of each star.

Hubble’s Field of View. Large telescopes often have small fields of view. For example, the Hubble Space Telescope’s (HST’s) advanced camera has a field of view that is roughly square and about 0.06° on a side. a. Calculate the angular area of the HST’s field of view in square degrees. b. The angular area of the entire sky is about 41,250 square degrees. How many pictures would the HST have to take with its camera to obtain a complete picture of the entire sky?
