ETA Carina

The Carina Nebula (catalogued as NGC 3372) is located in the Carina–Sagittarius Arm. Located approximately 8,500 light-years (2,600 pc) from Earth, this emission nebula (so-called because it emits light) is one of the largest that can be observed from Earth. Although it is four times as large as and even brighter than the famous Orion Nebula, the Carina Nebula is much less well known due to its location in the southern sky
