Just shy of Halloween, the moon has completed a strange cosmic ritual with the eye of Taurus.
Late Tuesday night, the star Aldebaran, the fiery eye of the bull constellation, was occulted by the moon. Occultations, in astronomical terms, occur when one celestial body passes between Earth and another cosmic object, hiding the latter from view.
Spectators in the eastern half of the United States could view the cosmic event through simple telescopes. As the waning gibbous moon moved across the sky, Aldebaran disappeared behind it. Later, having passed through the moon’s dark limb, the star appeared to materialize out of thin air.
