Amazing Sunset Sky Show
 
June 11, 2015: If you love stargazing, there's a date you need to mark on your
calendar.  It's June.
 
That's right, the whole month!
 
Throughout the month of June 2015, the two brightest planets in the night sky,
Venus and Jupiter, are going to converge for a jaw-dropping close encounter.
You don't want to miss any of the action.

Venus and Jupiter are converging for a must-see close encounter at the end of
June. It could be the best backyard sky show of 2015.  Play the video
 
When the sun goes down, step outside and look west.  You don't have to wait
until the sky fades to black.  Venus and Jupiter are so bright, you can see
then shining through the twilight.  In fact, some people say the planets are
especially beautiful when they are surrounded by the cobalt hue of the early
evening sky--so don't wait.
 
During the first two weeks of June, Venus and Jupiter converge until they are
only about 10 degrees apart.  For reference, this means they would just fit
together inside the bowl of the Big Dipper.  You could hide them both,
simultaneously, behind the palm of your outstretched hand.
 
This is pretty close, but by the end of the month this distance will shrink by
a factor of 30.
 
In fact, every night in June, the separation between Venus and Jupiter will
visibly shrink.
 
One good night to check on their progress is June 12th.  After dark, scan the
sky around Venus with binoculars.  You can see the Beehive Star cluster! Venus
will be passing right by it.
 
On June 18th, Venus and Jupiter will be only 6 degrees apart.  Now you can
hide the two behind just two or three of your fingers with your arm
outstretched.
 
On June 19th, something exciting happens: the crescent Moon joins the show. On
that evening, the Moon, Venus and Jupiter will form a bright isosceles
triangle in the sunset sky. Isosceles means that two sides of the triangle are
the same length.  This is how most sky watchers in North America will see it.
 
One night later, on June 20th, the vertices rearrange themselves, forming yet
another isosceles triangle. Never has a geometry lesson been so beautiful.
 
The nights of June 19th and 20th, by the way, are good nights to look through
a telescope. Even a small telescope will show you the fat crescent phase of
Venus, the cloudtops and largest moons of Jupiter, and the rugged terrain of
Earth's own Moon. Swing your optics around the triangle for a fast-paced
heavenly show.
 
The main event occurs on June 30th. On that night, Venus and Jupiter will be a
jaw-dropping 1/3rd of a degree apart.  That's less than the diameter of a full
Moon.  You'll be able to hide the pair not just behind the palm of your
outstretched hand, but behind your little pinky finger.
 
Wow. Here's hoping you spend a lot of time under the stars and planets in June.
