Who discovered the Orion Nebula?

The Orion Nebula (M42, NGC1976) is a reflection nebula located in the constellation Orion. It was discovered by the Dutch astronomer Huygens in 1656. It has a diameter of about 16 light-years, an apparent magnitude of 4, and is 1,500 light-years away from the earth. The same location is also near the Chinese star names "Fa Yi", "F Er" and "F San".

The Orion Nebula is visible to the naked eye and is one of the indicators for identifying Orion. The Orion Nebula is one of the most important objects for astrophotography enthusiasts and large telescopes of observatories. On September 30, 1880, Henry Draper had successfully photographed the nebula next to the Quadruple Star of Orion for 15 minutes. Now we can photograph the pink light of the entire Orion and the Orion Nebula with a fixed exposure of five minutes using a wide-angle lens camera. .

The quadruple star in the center of the nebula is one of the targets for observation and research on the birth of stars. The detail of photographing the nebula next to it is also a test of astronomical photography, telescope resolution and post-processing skills.
