NGC_2120 is a bright planetary nebula located in the constellation of Hydra. It was discovered by the astronomer John Herschel in 1834 and is approximately 3,000 light-years away from Earth. The nebula is known for its striking colors and intricate structure, which are the result of gases ejected from a dying star. The central star of NGC_2120 is a hot, luminous object that emits intense ultraviolet radiation, causing the surrounding gas to glow. This nebula is part of a larger class of astronomical objects known as planetary nebulae, which represent a late stage in the evolution of stars similar to our Sun.
