Annotated Image of NGC 604
On the western (right) side of NGC 604, the amount of hot gas found in the bubbles
corresponds to about 4300 times the mass of the sun. This value and the
brightness of the gas in X-rays imply that the western part of NGC 604 is
entirely powered by winds from the 200 hot massive stars. The implication is that in
this area of NGC 604, none or very few of the massive stars must have
exploded as supernovas. The situation is different on the eastern (left) side of NGC 604. On this
side, the X-ray gas contains 1750 times the mass of the sun and winds from
young stars cannot explain the brightness of the X-ray emission. The
bubbles on this side of the cluster appear to be much older and were likely
created and powered by young stars and supernovas in the past.

Chandra X-ray Image of NGC 604
This Chandra X-ray image shows a divided neighborhood where some 200 hot, young, massive stars reside. Bubbles in the cooler gas and dust have been generated by powerful stellar winds, which are then filled with hot, X-ray emitting gas. Scientists find the amount of hot gas detected in the bubbles on the right side corresponds to the amount entirely powered by winds from the 200 hot massive stars. The situation is different on the left side where the amount of X-ray gas cannot explain the brightness of the X-ray emission. The bubbles on this left side appear to be much older and were likely created and powered by young stars and supernovas in the past.

Hubble Optical Image of NGC 604
NGC 604 is similar to familiar star-birth regions in our Milky Way galaxy, such as the
Orion Nebula, but it is vastly larger in extent and contains many more recently formed stars. It contains more than 200 brilliant blue stars within a cloud of glowing gases some 1,300 light-years across, nearly 100 times the size of the Orion Nebula.
