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.
