巨大的恒星摇篮NGC 604位于大约300万光年外的螺旋星系M33的怀抱中，直径约为1300光年。这几乎是银河系猎户座星云的100倍，猎户座星云是距离地球最近的大型恒星形成区。事实上，在本星系群内的恒星形成区域中，NGC 604的大小仅次于剑鱼座30，也被称为大麦哲伦星云中的狼蛛星云。詹姆斯·韦伯太空望远镜NIRCam拍摄的这张令人惊叹的红外图像中，ngc604中充满了洞穴状的气泡和空洞。它们是由该地区200多颗热的、大质量的年轻恒星产生的高能恒星风雕刻而成的，这些恒星都还处于生命的早期阶段。

Located some 3 million light-years away in the arms of nearby spiral galaxy M33, giant stellar nursery NGC 604 is about 1,300 light-years across. That's nearly 100 times the size of the Milky Way's Orion Nebula, the closest large star forming region to planet Earth. In fact, among the star forming regions within the Local Group of galaxies, NGC 604 is second in size only to 30 Doradus, also known as the Tarantula Nebula in the Large Magellanic Cloud. Cavernous bubbles and cavities in NGC 604 fill this stunning infrared image from the James Webb Space Telescope's NIRCam. They are carved out by energetic stellar winds from the region's more than 200 hot, massive, young stars, all still in early stages of their lives.
