在右边，穿着蓝色衣服的是昴宿星。昴宿星团也被称为七姐妹星团和M45星团，是天空中最明亮、最容易看到的疏散星团之一。昴宿星团包含3000多颗恒星，距离我们约400光年，直径只有13光年。围绕恒星的是一个由细尘埃组成的壮观的蓝色反射星云。一个常见的传说是，自从星团被命名后，其中一颗较亮的恒星就消失了。在左边，闪耀着红色光芒的是加州星云。加利福尼亚星云因其形状而得名，它比昴星团暗淡得多，因此很难看到。这团红色发光的氢气也被称为NGC 1499，距离我们大约1500光年。虽然它们之间可以容纳大约25个满月，但这张广角、深景深合成的特色图像将它们都捕捉到了。仔细观察这张深度图像也会发现恒星形成区域IC 348和分子云LBN 777（小鹰星云）。跳跃宇宙：随机APOD生成器

On the right, dressed in blue, is the Pleiades. Also known as the Seven Sisters and M45, the Pleiades is one of the brightest and most easily visible open clusters on the sky. The Pleiades contains over 3,000 stars, is about 400 light years away, and only 13 light years across. Surrounding the stars is a spectacular blue reflection nebula made of fine dust. A common legend is that one of the brighter stars faded since the cluster was named. On the left, shining in red, is the California Nebula. Named for its shape, the California Nebula is much dimmer and hence harder to see than the Pleiades. Also known as NGC 1499, this mass of red glowing hydrogen gas is about 1,500 light years away. Although about 25 full moons could fit between them, the featured wide angle, deep field image composite has captured them both. A careful inspection of the deep image will also reveal the star forming region IC 348 and the molecular cloud LBN 777 (the Baby Eagle Nebula). Jump Around the Universe: Random APOD Generator
