[1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 December 27 [2] The Great Carina Nebula Image Credit & Copyright [3] : Maicon Germiniani [4] Explanation: A jewel of the southern sky, the Great Carina Nebula [5] , also known as NGC 3372, spans over 300 light-years, one of our galaxy's [6] largest star forming regions. Like the smaller, more northerly Great Orion Nebula [7] , the Carina Nebula is easily visible to the unaided eye, though at a distance of 7,500 light-years it is some 5 times farther away. This gorgeous telescopic close-up [8] reveals remarkable details of the region's central glowing filaments of interstellar gas [9] and obscuring cosmic dust [10] clouds. The field of view is over 50 light-years across. The Carina Nebula is home to young, extremely massive stars, including the stars of open cluster Trumpler 14 [11] (above and left of center) and the still enigmatic variable Eta Carinae [12] , a star with well over 100 times the mass of the Sun. Eta Carinae is the brightest [13] star, centered here just below the dusty Keyhole Nebula [14] (NGC 3324). While Eta Carinae itself maybe on the verge of a supernova explosion, X-ray images indicate that the Great Carina Nebula has been a veritable supernova factory [15] .
