Image Data

Designation NGC 3576 (right) and NGC 3603
Constellation Carina (Car)
Description The color difference between these two objects is striking. The reason: NGC 3603 on the left is twice as distant, which is documented by the blue extinction in its color as compared to its 'neighbour' NGC 3576.  The latter with its characteristic loops formed by stellar winds also contains a number of prominent Bok Globules, dark dense stellar nurseries.  NGC 3603 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).  Here is an image in the monochromatic light of ionized hydrogen (H-Alpha) of the same field.
