The Rosette Nebula spans a distance of about 100 lightyears across and is located 5,000 lightyears from Earth in the Monoceros constellation.

Catalogued as NCG 2237, the Rosette Nebula more than lives up to its informal nickname, as its circular shape and deep, dark centre gives it a floral appearance.

At the centre of the nebula is NGC 2244, a group of stars that form a gravitationally bound open star cluster thought to be about 4 million years old.

These stars are emitting streams of charged particles known as stellar winds, carving out the gas and dust at the centre of the nebula and earning the cosmic cloud its Rosette nickname.

The surrounding gas that forms a ring around the dark centre is glowing because it is being blasted by radiation from nearby stars, making the Rosette Nebula an emission nebula.

Below is a selection of images of the Rosette Nebula captured by BBC Sky at Night Magazine readers and astrophotographers from around the world.
