 Here we are zooming into the giant Corina Nebula. It is a very large, bright nebula that surrounds several clusters of stars. The nebula itself measures some 260 light years across. That's about 7 times the size of the Orion Nebula. Let's take a look at some of the amazing structures contained in Corina. NGC 3324 is located at the northwest corner. The glowing nebula has been carved out by intense ultraviolet radiation and stellar winds from several hot, young stars. The image also reveals dramatic dark towers of cool gas and dust that rise above the glowing wall. This image from Hubble shows the tip of a three light year long pillar bathed in the glow of light from hot massive stars off the top of the image. Scorching radiation and fast stellar winds are sculpting the pillar and causing new stars to form within it. Although the stars themselves are invisible, one of them is providing evidence of its existence. Thin jets of material can be seen traveling to the left and to the right of a dark notch in the center of the pillar. Astronomers estimate that the jets are moving at speeds of up to 1.4 million kilometers per hour. That's 850,000 miles per hour. These one light year pillars of cold hydrogen and dust are created by violent stellar winds and powerful radiation from massive stars. Here's a three light year tall pillar of gas and dust that is being eaten away by the brilliant light from nearby stars. The pillar is also being assaulted from within as infant stars, buried inside, fire off jets of gas that can be seen streaming from the towering peaks.
