Title:[0248] The loops of the NGC 3576 nebula Caption:The stars that evidently excite this unusual nebula are not seen on this photograph. They are hidden in the dusty cloud at the base of the huge loops of material that have been blown out by radiation pressure and stellar winds from the concealed stars. Silhouetted against the tenuous loops are clouds of dust with bright rims, which indicate the direction of the stars which power the nebula. This large complex of gas and dust is at about the same distance as the Eta Carinae Nebula, about 8,000 light years away.
