獵戶座大星雲是附近一個巨大的恆星誕生區，可能是所有天文星雲中最著名的一個。 在這個星雲中，熾熱的氣體環繞著炙熱的年輕恆星，它們位於僅 1500 光年遠的巨大星際分子云的邊緣。 在以氧和氫的發射為亮點的指定顏色深層影像中，塵埃和氣體的縷狀和片狀尤為明顯。 獵戶座大星雲位於獵戶座中易於識別的三顆恆星帶附近。 獵戶座大星雲除了包含一個明亮的開放星團--梯形星團之外，還包含許多恆星苗圃。 這些苗圃中含有大量氫氣、炙熱的年輕恆星、螺旋體和高速噴射物質的恆星噴流。 獵戶座星雲也被稱為 M 42 ，橫跨約 40 光年，與太陽位於銀河系的同一旋臂上。
原文：The Great Nebula in Orion, an immense, nearby starbirth region, is probably the most famous of all astronomical nebulas. Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away. In the featured deep image in assigned colors highlighted by emission in oxygen and hydrogen, wisps and sheets of dust and gas are particularly evident. The Great Nebula in Orion can be found with the unaided eye near the easily identifiable belt of three stars in the popular constellation Orion. In addition to housing a bright open cluster of stars known as the Trapezium, the Orion Nebula contains many stellar nurseries. These nurseries contain much hydrogen gas, hot young stars, proplyds, and stellar jets spewing material at high speeds. Also known as M42, the Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.
