Another consequence of this want of air is that absolute darkness reigns where the sun's rays do not penetrate. That which on earth is called diffusion of light, that luminous matter which the air holds in suspension, which creates the twilight and the daybreak, which produces the umbrae and penumbrae, and all the magic of chiaro-oscuro, does not exist on the moon. Hence the harshness of contrasts, which only admit of two colors, black and white. If a Selenite were to shade his eyes from the sun's rays, the sky would seem absolutely black, and the stars would shine to him as on the darkest night. Judge of the impression produced on Barbicane and his three friends by this strange scene! Their eyes were confused. They could no longer grasp the respective distances of the different plains. A lunar landscape without the softening of the phenomena of chiaro-oscuro could not be rendered by an earthly landscape painter; it would be spots of ink on a white page-- nothing more.
This aspect was not altered even when the projectile, at the height of 80@, was only separated from the moon by a distance of fifty miles; nor even when, at five in the morning, it passed at less than twenty-five miles from the mountain of Gioja, a distance reduced by the glasses to a quarter of a mile. It seemed as if the moon might be touched by the hand! It seemed impossible that, before long, the projectile would not strike her, if only at the north pole, the brilliant arch of which was so distinctly visible on the black sky.
Michel Ardan wanted to open one of the scuttles and throw himself on to the moon's surface! A very useless attempt; for if the projectile could not attain any point whatever of the satellite, Michel, carried along by its motion, could not attain it either.
At that moment, at six o'clock, the lunar pole appeared. The disc only presented to the travelers' gaze one half brilliantly lit up, while the other disappeared in the darkness. Suddenly the projectile passed the line of demarcation between intense light and absolute darkness, and was plunged in profound night!
THE NIGHT OF THREE HUNDRED AND FIFTY-FOUR HOURS AND A HALF
At the moment when this phenomenon took place so rapidly, the projectile was skirting the moon's north pole at less than twenty-five miles distance. Some seconds had sufficed to plunge it into the absolute darkness of space. The transition was so sudden, without shade, without gradation of light, without attenuation of the luminous waves, that the orb seemed to have been extinguished by a powerful blow.
"Melted, disappeared!" Michel Ardan exclaimed, aghast.
Indeed, there was neither reflection nor shadow. Nothing more was to be seen of that disc, formerly so dazzling. The darkness was complete. and rendered even more so by the rays from the stars. It was "that blackness" in which the lunar nights are insteeped, which last three hundred and fifty-four hours and a half at each point of the disc, a long night resulting from the equality of the translatory and rotary movements of the moon. The projectile, immerged in the conical shadow of the satellite, experienced the action of the solar rays no more than any of its invisible points.
In the interior, the obscurity was complete. They could not see each other. Hence the necessity of dispelling the darkness. However desirous Barbicane might be to husband the gas, the reserve of which was small, he was obliged to ask from it a fictitious light, an expensive brilliancy which the sun then refused.
"Devil take the radiant orb!" exclaimed Michel Ardan, "which forces us to expend gas, instead of giving us his rays gratuitously."
"Do not let us accuse the sun," said Nicholl, "it is not his fault, but that of the moon, which has come and placed herself like a screen between us and it."
"It is the sun!" continued Michel.
"It is the moon!" retorted Nicholl.
An idle dispute, which Barbicane put an end to by saying:
"My friends, it is neither the fault of the sun nor of the moon; it is the fault of the projectile, which, instead of rigidly following its course, has awkwardly missed it.
