Before dawn tomorrow – July 29, 2016 – look east to see the lunar crescent partnering up with Aldebaran, the brightest star in the constellation Taurus the Bull. Our sky chart at top shows the view as seen from mid-northern North American latitudes, where the moon and Aldebaran will be a hair’s-breadth apart on the sky’s dome.
Elsewhere around the world – Europe, Africa, Asia, Australia and New Zealand – the moon and Aldebaran will be farther apart from one another during the predawn hours on July 29. The moon’s illuminated side will be pointing in the direction of Aldebaran, and in the moon’s direction of travel relative to the backdrop stars of the zodiac.
If you live in Texas, Mexico or Central America, you can actually watch the moon occult – cover over – Aldebaran in the predawn hours on July 29, 2016. Aldebaran disappears behind the moon’s illuminated side and reappears on the moon’s dark side.
