The 'worm' supermoon lights up night skies around the world and will only get brighter as it reaches its peak tonight

Spectacular pictures of the 'worm' supermoon have been captured lighting up the night sky by photographers around the world.

The March full moon will reach peak fullness tonight at 5:48pm GMT - but it appeared full from Sunday night and will still be visible through to Tuesday, The Daily Mail reports.

The Worm Moon will be 'spectacularly bright', according to the Old Farmer's Almanac, and appear about seven per cent larger than a normal full moon.

A supermoon occurs when the full moon nearly coincides with perigee – the point in the orbit of the moon at which it is nearest to the Earth. 

At perigee a supermoon can appear as much as 14 per cent larger and 30 per cent brighter than normal, when viewed from Earth, depending on the time of year.

Full moon names, which are used to describe the supermoons, were historically used to track the seasons and therefore are closely related to nature.

‘Worm Moon’ is the common name for March’s full moon because at the time it appears the ground begins to soften and heaps of soil left by worms start to appear.

This invites the return of birds to feed, which is seen as a sign of springtime  starting to return after a long winter.

There will be two additional supermoons this season – April 8, when a ‘Pink Moon’ will be 221,851 miles from Earth, and the ‘Flower Moon’ on May 7, at 224,429 miles away.

The Worm Moon is the second of the supermoons to grace the sky this year, following the ‘Snow Moon’ in early February, so-called as it often coincides with heavy snowfall.

The supermoon on November 14, 2016 was the closest full supermoon since January 26, 1948, and will not be surpassed until November 25, 2034, according to Earth Sky.

The closest full supermoon of the 21st century will occur on December 6, 2052.

Astronomers differ on what they believe constitutes a ‘supermoon’ – however, the original definition as coined by astrologer Richard Nolle in 1979 puts it as a full moon or new moon that comes within 90 per cent of its closest approach to Earth.

If possible, the best time to view the full moon is when it is close to the horizon, due to an optical illusion that makes it appear bigger due to its relative size compared to buildings, trees and other objects in the foreground.

Astronomers advise photographers to download apps and maps to track the progress of the moon across the sky, in order to make sightings easier.
