Stargazers have a chance to see a rare blue moon phenomenon in the skies over Bedfordshire this evening, something that won’t happen again until 2018.

The sight is so rare, the phrase ‘once in a blue moon’ was coined because of it.

But rather than the moon actually changing colour, a blue moon refers to when two full moons appear in the same calendar month.

The first full moon was spotted on 1 July and the second will appear on the last day of the month – Friday, July 31.

Website lists the following information on blue moons: “A Moon that actually looks blue, however, is a very rare sight. The Moon, full or any other phase, can appear blue when the atmosphere is filled with dust or smoke particles of a certain size.

“Eruptions like on Mount Krakatoa, Indonesia (1883), Mount St. Helens (1980) and Mount Pinatubo (1991) are all known to have caused blue moons.”

This appearance is the first such occurrence in three years since the last blue moon month in August 2012, the next will not be until January 2018.

Astronomers predict it will only happen on 12 occasions between now and 2043.
