His older brother Henry was the one who suggested naming the moons of Mars after Phobos and Deimos, the Greek gods of fear and terror. 48 THE CASE FOR PLUTO So right after breakfast, Madan passed along Venetia’s suggestion in a note to Oxford professor Herbert Hall Turner, who had once been Britain’s astronomer royal. Turner got Madan’s message after returning from a Royal Astronomical Society meeting where Planet X’s discovery was topic A. The eminent astronomer was impressed with the girl’s suggestion.

His fascination with exotic frontiers, and his high regard for the scientific frontier, hinted at the turn he took toward astronomy in the 1890s. It all started with Italian astronomer Giovanni Schiaparelli and his observations of canali on Mars, features that looked like lines crisscrossing the Red Planet’s disk. Lowell saw Schiaparelli as a nineteenth-century Columbus who had discovered a new civilization through the sights of his telescope, and he resolved to see the canals for himself when Mars made a close approach to Earth in 1894.

Under the right circumstances, a planet’s color can reveal an amazing amount about its composition. What you have to do is obtain a spectrum for the light reflected by the planet—a breakdown of the light that shows precisely which wavelengths are being reflected, and which are not. Every element has a characteristic spectral signature, and if your spectrograph is good enough to separate out those signatures, you can figure out which elements are present in which proportions. Unfortunately, the spectrographs weren’t nearly good enough in those days to analyze the faint light reflected by Pluto.
