Star-forming region NGC 604 contains more than 200 of the hottest, most massive kinds of stars (B-type and O-type stars), all in the early stages of their lives. There is no region quite like this within our own Milky Way, making NGC 604 a perfect window for astronomers to study young, massive stars.⁣

At the center of the image is a nebula on the black background of space. The nebula is comprised of clumpy, red, filamentary clouds. At the center-right of the red clouds is a large cavernous bubble, and at the center of the bubble there is an opaque blueish glow with speckles of stars. At the edges of the bubble, the dust is white. There are several other smaller cavernous bubbles at the top of the nebula. There are thousands of stars that fill the surrounding area outside of the nebula, most of them are yellow or white – at 11 o’clock and 6 o’clock there are extremely bright stars with eight diffraction spikes. There are also some smaller, red stars and a few disc-shaped galaxies scattered about the image.⁣
