Halloween fans will be treated to a “once in a blue moon” phenomenon this year as the night sky will be lit up by a spooky full moon.
Its the first time we’ve seen a full moon on October 31 in almost two decades, with the last one in 2001 according to experts.
Astrologers say a full moon on Halloween only happens every 18 to 19 years, meaning this could be the creepiest Halloween until at least 2038.
And while this year’s celebrations will undoubtedly be different to usual, the ‘blue moon’ will certainly make the holiday as eerie as ever.
While the name might make you think you’re going to see a blue-tinted moon in the sky, a full moon is actually called a ‘blue moon’ when it is the second in a single calendar month – because it’s so rare.
According to Nasa, a full moon on Halloween won’t happen again for almost two decades so this is certainly a great opportunity for stargazers.
When the phrase “once in a blue moon” was coined, it meant something so rare you’d be lucky (or unlucky) to see in your lifetime, according to Nasa.
The moon will also be a “micro moon” – a full moon that occurs when it is exceptionally far away from Earth.
And luckily, people in Europe are expected to get a good view of the event, so hopefully you’ll be able to enjoy it as part of your Halloween activities.
