January 27, 2009--In this composite image, Chandra X-Ray Observatory data (blue) is combined with visible-light data from the Hubble Space Telescope (red and green) to reveal a divided neighborhood in the nearby M33 galaxy which houses some 200 huge, hot stars.

On the right side of the image, hot gas found in bubbles is about 4,300 times the mass of the sun, and young stars completely power the area's winds.

On the left side, the bubble gas is 1750 times the sun's mass and was likely created by young stars and supernovae in the past.
