Famous quotes containing the words planets and/or confirmed:

    Perhaps when distant people on other planets pick up some wave-length of ours all they hear is a continuous scream.
    Iris Murdoch (b. 1919)

    He prayed more deeply for simple selflessness than he had ever prayed before—and, feeling an uprush of grace in the very intention, shed the night in his heart and called it light. And walking out of the little church he felt confirmed in not only the worth of his whispered prayer but in the realization, as well, that Christ had become man and not some bell-shaped Corinthian column with volutes for veins and a mandala of stone foliage for a heart.
    Alexander Theroux (b. 1940)
