The vast Carina Nebula (Eta Carinae) is the jewel of the southern hemisphere. This giant nebula is located between 6,500 and 10,000 light years away in the Sagittarius arm of our galaxy. It is cataloged as NGC 3372. This is one of the largest regions of sta formation in our galaxy. It is also the HII Is called HII regions, regions consist of clouds composed mainly of hydrogen and most of the atoms are ionized and extending over several light years. Ionization is produced by the proximity of one or more hot star of spectral type O or B, which radiate strongly in the extreme ultraviolet and ionizing the surrounding gas from which these stars formed.  region (region of ionized hydrogen), the brightest of the Milky Way. The small dark nebula called the "Keyhole (Keyhole)" is the absorbing cloud in the center of the nebula. The Carina Nebula although situated very far from us, is bright enough to be seen with the naked eye, but only from the southern hemisphere. These fantastic pillars of radiating dust and gas, interspersed with new stars were mainly shaped by the intense wind and radiation the main star Eta Carinae. 3D video shows the giant clouds of dust and gas of the Carina.

nota: Eta Carinae was in the 1830s, one of the brightest stars in the sky, then faded dramatically. Eta Carinae could explode in a supernova definitely in the next thousand years. Its luminosity is about four million times that of the Sun and its estimated weight of about 100 to 150 solar masses. This star is one of the most massive star discovered. Eta Carinae is near the keyhole nebula, NGC 3324.
