The Ring Nebula, also known as M57, is a planetary nebula found 2,000 lightyears away in the Lyra constellation.

It's special because it's one of the most iconic and beautiful planetary nebulae known to astronomers and astrophotographers, angled towards Earth so we can marvel at its majestic appearance.

The Ring Nebula is also known at M57, the 57th entry in Charles Messier's famous catalogue of deep-sky objects, known as the Messier Catalogue.

It was discovered by French astronomer Antoine Darquier de Pellepoix in January 1779.

What is the Ring Nebula?

The Ring Nebula is a planetary nebula.

Planetary nebulae like the Ring Nebula have nothing to do with planets, but are a result of an ageing, Sun-like star ejecting cosmic material into space, producing a spherical, puffed-out shape.

The Ring Nebula is no different: it has a dying star at its centre and this is the reason it has a large, ring-like structure.

Observations with the Hubble Space Telescope revealed that the Ring Nebula actually consists of an inner, rugby ball-shaped region of gas seen end-on from Earth (blue in the image below) that is piercing the outer red ring-shaped material.

In August 2023, astronomers released a beautiful James Webb Space Telescope image of the Ring Nebula that shows off the object in wonderful detail.

The Webb images of the Ring Nebula show it in infrared, giving astronomers a new look at this familiar object.

How to find the Ring Nebula

The nebula lies south of the bright star Vega, which makes up the famous asterism the Summer Triangle (one of the best summer constellations and asterisms, in our opinion).

A good trick for locating the Ring Nebula is to find stars Sulafat and Sheliak in Lyra.

The Ring Nebula sits three-fifths of the way along the line from Sulafat the second brightest star in the contellation, towards Sheliak.
