Question

Quizplus · Accepted Answer

Spectrometer is the best choice as it can measure the spectrum of light coming from the planet and identify the specific wavelengths that relate to methane gas. This method allows us to detect gases from a distance without the need for a space probe or physical presence on the planet. A CCD or photographic plate holder could capture images of the planet, but they would not provide information about the planet's atmospheric gases.
