This is a full image of the Carina nebula
The large bright spot near the middle of this image is Eta Carinae, a hypergiant star.
These pillars of gas and dust are resisting erosion from stellar winds.
The glowing "caterpillar" to the right is a globule of cold dust and gas that is illuminated by stellar radiation.
For more concerning the Carina nebula, I would recommend visiting Hubblesite.org and going to their image tour.
