NGC2736 / Pencil Nebula

NGC 2736, also known as the Pencil Nebula, is a small, narrow, bright nebula in the constellation Vela (The Sail). It is a part of a more significant supernova remnant called Vela Supernova Remnant, which resulted from a supernova explosion about 11,000 to 12,300 years ago.

The Pencil Nebula is approximately 0.3 light-years long and is composed of ionized gas, mostly hydrogen, that emits light in the red and blue parts of the spectrum. The nebula is illuminated by the radiation from a nearby star, which ionizes the gas and causes it to glow. The nebula's shape is believed to be the result of the shock wave from the supernova explosion interacting with the surrounding interstellar medium.

The Pencil Nebula is not visible to the naked eye and can only be observed with a telescope. It was first discovered by the American astronomer Frank Elmore Ross in 1939, and its distinctive shape has made it a popular target for astrophotography.
