This Week’s Night Sky: Moon Eclipses the Bright Star Aldebaran
Sky-watchers can see the moon cover a star and look for a Mars, Jupiter, and Venus in a diagonal line.
All night, Earth’s lone natural satellite will appear nestled within the face of the bull that is marked by the bright Hyades star cluster. This loose association of hundreds of stars is distinctly V-shaped, with the bright orange-colored Aldebaran star marking the mythical beast’s angry eye.
Estimated to be about 152 light-years from Earth, the Hyades cluster is among the closest clusters to our solar system, making it also one of the most brilliant in our skies.
This stellar disappearing act is best seen with binoculars or a small telescope at a high magnification. Making the view dramatic, Aldebaran appears distinctly orange in color and is 68 light-years away, while our moon is a mere 1.23 light-seconds distant.
