image: Pekka Parviainen A Grand Pleiades Occultation on April 1st "Astronomers have tracked occultations for centuries. Aristotle told of the Moon covering Mars on April 4, 357 B.C. — proof that Mars was farther away than the Moon. If the Moon had an atmosphere, stars would gradually dim as the Moon's edge approached them, the same way the setting Sun dims before it reaches Earth's horizon."
