The best morning is May 11th, when Venus and Jupiter converge to form a tight pair only 1/2
o apart. (Now you can hide them using no more than one finger.) Venus and
Jupiter are so bright you might think you've witnessed a double
supernova beaming through the morning twilight. But, no, it's just the
two brightest planets in our own solar system.
Keep an eye on Venus in particular. As the sun rises and the sky
fills with morning blue, the Goddess of Love does not fade away. You can
actually see Venus in broad daylight if you know where to look.
May 11th is just the beginning. Throughout the month, the quartet
of worlds will rearrange themselves on a daily basis, forming different
shapes in the pre-dawn sky.
On May 13th, for instance, Mercury, Venus and Jupiter form a
bright celestial triangle--almost equilateral. It's a geometry lesson
before breakfast. On May 20th, a new triangle will appear. This time the
vertices are Mars, Venus, and Mercury. Observing tip: Mars is not as
bright as the others. Binoculars may be required to help you find and
fully appreciate the red planet in morning twilight.
The show comes to an end on May 30th when an exquisite crescent
Moon joins the four planets for a Grand Finale--five heavenly lights
dotting the eastern sky all at once.
