狮子星云是仙王座的真正统治者吗？这个强大的猫状星云由两颗大质量恒星提供能量，每颗恒星的质量都是太阳的20多倍。由膨胀的电离气体壳形成，星云的高能物质不仅发光，而且密度足够大，可以通过引力收缩形成恒星。狮子星云的角大小，正式命名为Sh2-132，比满月略大。这个标志性的气体区域位于一个以希腊神话中埃塞俄比亚国王命名的星座中，距离我们约1万光年。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

Is the Lion Nebula the real ruler of the constellation Cepheus? This powerful feline appearing nebula is powered by two massive stars, each with a mass over 20 times greater than our Sun. Formed from shells of ionized gas that have expanded, the nebula's energetic matter not only glows, but is dense enough to contract gravitationally and form stars. The angular size of the Lion Nebula, officially named Sh2-132, is slightly greater than that of the full moon. The gaseous iconic region resides about 10,000 light years away in a constellation named after the King of Aethopia in Greek mythology.
