Friday’s Blue Moon Can Be Viewed Live Online

Friday’s blue moon will be the last time people get the chance to see the lunar event for three years, but even people living under cloudy skies or who can’t get outside will have a chance to view it.

The blue moon will be shown by the Slooh Space Camera, which begins its broadcast starting at 6 p.m. with a feed from the Prescott Observatory in Arizona and an observatory in the Canary Islands.

A word of warning, the New York Daily News writes — don’t expect to see any color change with the moon.

He popularized his mistake when he wrote an article for Sky & Telescope magazine titled “Once in a Blue Moon.” From there the incorrect definition became the common usage, Space.com reported.

The Slooh Space Camera broadcast of the blue moon will honor another lunar legend, astronaut Neil Armstrong. His funeral is coincidentally the same day, TIME reported. It’s apparently the kind of coincidence that happens once in a blue moon.
