Galileo’s small telescope showed that the Milky Way was composed of a multitude of stars that were too faint to be resolved individually with the unaided eye. Unlike the planets, which when magnified through a telescope displayed a small but distinct disk, the stars remained as point-like objects. This, along with the fact that the stars displayed no discernable parallax through the instruments in use in the seventeenth century, suggested that the stars were at a truly unimaginable distance from the Solar System. French philosopher Blaise Pascal (1623–1662) conveys a vivid sense of the human reaction to this new-found scale of the Universe when in his Pensées (Thoughts, 1670) he writes of a man without God: “engulfed in the infinite immensity of spaces of which I am ignorant and which know me not… The eternal silence of these infinite spaces frightens me.”
