The Great Nebula in Carina was discovered in 1751 by Nicolas Louis de Lacaille, during his time in Cape Town. It is a vast bright nebula, visible to the naked eye and covering an area in the sky several times larger than the full Moon.
There are a number of interesting objects within the Carina Nebula, including the bright hyper-giant star Eta Carina, the dark Keyhole nebula, the Homunculus nebula, the “Mystic Mountain” dust-gas pillar, and several open clusters of stars.
It is between 6500 and 10000 light years away, and shine with a surface magnitude of 1, making it easily visible to the naked eye.
