The Great Carina Nebula (NGC 3372), is the most famous star-forming region of the southern sky, spanning more than 100 light-years and is visible to the naked eye as a glowing patch in the Milky Way.
The Nebula plays home for thousands of stars similar in mass to the sun and 70 O-type stars, which are stars with a mass between 15 and 150 times the mass of the sun. O-stars burn hot and bright and die young-within 10 million years.
This image shows the area surrounding the Keyhole Nebula (NGC 3324) and spans about 40 light-years.
Several astronomical objects can be seen in the image : to the bottom left of the image is one of the most impressive binary stars in the Universe, Eta Carinae. Adjacent, lie the Keyhole Nebula and Homunculus Nebula – material ejected from the star during its Great Eruption in the 19th century. The collection of very bright, young stars above and to the right of Eta Carinae is the open star cluster Trumpler 14. A second open star cluster, Collinder 228 is also seen in the image, just below Eta Carinae.
