獅子星雲是仙王座真正的統治者嗎? 這個看起來像貓科動物的強大星雲由兩顆大質量恆星驅動,每顆恆星的質量都比太陽大 20 多倍。 星雲由電離氣體外殼膨脹而成,其高能物質不僅會發光,而且密度大到足以在引力作用下收縮並形成恆星。 獅子星雲的正式名稱為 Sh 2 - 132 ,其角度大小略大於滿月。 這個氣態標誌性區域位於大約 1 萬光年外的一個星座中,該星座以希臘神話中的伊索比亞王命名。 你的天空驚喜你的生日是哪一天?
原文: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.
