卡拉菲亚女王的神秘岛屿会在太空中存在吗？也许不是，但碰巧这个分子空间云的轮廓与美国加利福尼亚州的轮廓相呼应。我们的太阳位于银河系的猎户座臂内，距离加利福尼亚星云只有大约1000光年。这个经典的发射星云也被称为NGC 1499，长约100光年。在这张特色图片上，加州星云最突出的辉光是氢原子与长期丢失的电子重新结合的红光，这些电子被高能星光剥离（电离）。星云右边明亮、炽热、带蓝色的西仙座是最有可能提供高能恒星光并电离大部分星云气体的恒星。加州星云是天文摄影师的常规目标，在黑暗的天空下，用宽视场望远镜可以发现它，它位于英仙座附近，离昴宿星团不远。探索你的宇宙：随机APOD生成器

Could Queen Calafia's mythical island exist in space? Perhaps not, but by chance the outline of this molecular space cloud echoes the outline of the state of California, USA. Our Sun has its home within the Milky Way's Orion Arm, only about 1,000 light-years from the California Nebula. Also known as NGC 1499, the classic emission nebula is around 100 light-years long. On the featured image, the most prominent glow of the California Nebula is the red light characteristic of hydrogen atoms recombining with long lost electrons, stripped away (ionized) by energetic starlight. The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei just to the right of the nebula. A regular target for astrophotographers, the California Nebula can be spotted with a wide-field telescope under a dark sky toward the constellation of Perseus, not far from the Pleiades.
