About this Image
These rarely imaged nebulae are situated between the Southern Cross and Eta-Carinae. Both nebulea are very active starforming regions and emit strongly in the light of ionized hydrogen (H-Alpha).
They are 7.000 and 14.000 light years away respectively. NGC 3576 with its characteristic loops formed by stellar winds also contains a number of prominent Bok Globules,
dark dense stellar nurseries. NGC 3603 (left) may well be the largest nebula in our galaxy and features concentrations of young, hot and massive Wolf-Rayet stars, much like at the center of the Tarantula Nebula (NGC 2070).
