Blue Moon of 2015 Thrills Skywatchers with Lunar Beauty (Photos)
The second full moon of July wowed skywatchers around the world - and even in space - on Friday, offering the lunar treat of a so-called Blue Moon that won't be seen again until 2018.
NASA and Space.com readers across the United States and abroad captured amazing photos of the Blue Moon on Friday (July 31), but perhaps the most remote view came from space.
"Once in a #BlueMoon. When in space 4 a [year] everything is possible," NASA astronaut Scott Kelly wrote on Twitter while posting a photo of the full moon. Kelly is spending a year in space aboard the International Space Station. Friday was his 126th day in orbit. [Video: Science of the Blue Moon Explained]
Friday's full moon followed just a few weeks after the first full moon of the month, on July 1, meeting. The "two full moons in a month" definition of a Blue Moon, which became popular in the 20th century, is actually one of two classifications for the lunar sight. The term originally referred to the third full moon in a season that had four full moons, a special event since most three-month seasons have just three full moons (one a month).
The next Blue Moon will occur in 2018 on Jan. 31 and be promptly followed by a second Blue Moon on March 31. Both months in that year have two full moons, according to EarthSky.org.
But definitions aside, Friday's Blue Moon full moon appeared to be an epic sight.
In Washington, D.C., NASA photographer Bill Ingalls captured spectacular views of a huge full moon rising behind the dome of the U.S. Capitol. He even caught an airplane flying across the face of the moon.
Photographer Shreenivasan Manievannan in South Carolina woke up extra early to photograph the full moon on Friday (the moon actually reached its full phase at 6:43 a.m. EDT (1043 GMT)).The result: breathtaking views of the Blue Moon over Table Rock Mountain in Table Rock State Park in the Blue Ridge Mountains.
"I started from home at 4 a.m. for an hour and half drive to capture the Blue Moon at its 100-percent fullness," Manievannan wrote in an email to Space.com. "As soon as I reached, the moon went behind the huge chunk of cloud, I wanted to wait it out to see if the moon will show up before it sets. And after half hour of wait, the moon decided to stop playing hide and seek with me to show itself over the Carolina mountains in all its glory"
In San Antonio, Texas, skywatcher Shenandoah Sanchez was excited to see the Blue Moon finally appear from behind clouds.
"Originally, blocked by haze and clouds as it rose above the horizon, the Blue Moon revealed itself just in time to be seen moving above the Tower of the America's in San Antonio, Texas," Sanchez wrote.
Some moon revelers like Elisa Barnes-Shizak, toasted the Blue Moon with a frosty beverage.
"Enjoying two blue moons in Caledonia, Mississippi," Barnes-Shizak wrote in an email. In her photo, a bottle of Blue Moon beer is held up next to the bright moon. The Blue Moon Brewing Company that makes the beer celebrated its 20th anniversary during the Blue Moonwith a series of events on Friday
Space.com also received photos from skywatchers from locales as far flung as Canada, Australia, Poland, Venezuela and Puerto Rico.
In Ohrid, Macedonia, amateur astronomer Stojan Stojanovski of the Ohrid Astronomy Association captured stunning views of the bright moon shining over the sea near Ohrid.
In Whitstable, England, skywatcher Rose Chapman used her phone to snap a picture of the Blue Moon and recall the memory of a family member lost during a previous Blue Moon.
"This Blue Moon is sentimental to me because the last one I saw was August 20, 2013," Chapman wrote in an email. "That day was my 35th birthday, and also the day we lost my husband's granddad. This is our first visit back to England since the funeral."
Chapman said that the Blue Moon clearly did not look blue to her eye, and with good reason. The "Blue Moon" moniker is just a name, with the moon usually shining as its bright white self and not actually appearing blue. In rare occasions, the moon can take on a blue hue due to ash in the atmosphere from volcanic eruptions, NASA officials have said.
