You 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 us
The Sloan Digital Sky Survey
O searches to see whether extra-terrestrial civilizations are sending any digitally recorded music our way
O searches for Trans-Neptunian objects, small icy bodies in the outer solar system, whose orbits sometimes
resemble Pluto's
O takes images and spectra of millions of objects, to find the positions and redshifts of as many galaxies and quasars
as possible
J'
O searches for planets around neighbor stars by looking for changing Doppler shifts in their spectra
O searches for supernova remnants that could have pulsars inside and then try to find the pulsars
