Last Blue Moon Until 2015 Visible on Friday Night,Live coverege to pay honour to Neil Armstrong

When a second full moon in a calendar month appears in the night sky, the occurrence is known as a 'Blue Moon'.

An article on Space.com said blue moons usually occur every 2.7 years, with some using the event to pay tribute to the late astronaut Neil Armstrong.

The web-based Slooh Space Camera, which showcases live views from various telescopes around the world, is hosting a special broadcast of the blue moon on Friday, beginning at 6 p.m. EDT (2200 GMT).It can be accessed by visiting the Slooh Space Camera's website at events.slooh.com.

Slooh officials also said viewers can also tune in on their IOS or Android mobile devices.

Since full moons occur every 29 days and the last one appeared on August 2, skywatchers are scheduled to witness a blue moon on Friday. This will be the first blue moon since March 2010, nearly 30 months ago.

Some countries will technically not be in Blue Moon status, but they will be able to view the full Moon nonetheless.

Most Blue Moons look pale gray and white, indistinguishable from any other Moon you’ve ever seen. Squeezing a second full Moon into a calendar month doesn’t change the physical properties of the Moon itself, so its color remains the same.

The next Blue Moon will be on July 31, 2015.
