Explanation: Surprisingly reminiscent of The Great Nebula in Orion, The Great Turkey Nebula spans this creative field of view. Of course if it were the Orion Nebula it would be our closest large stellar nursery, found at the edge of a large molecular cloud a mere 1,500 light-years away. Also known as M42, the Orion Nebula is visible to the eye as the middle “star” in the sword of Orion the Hunter, a constellation now rising in planet Earth’s evening skies. Stellar winds from clusters of newborn stars scattered throughout the Orion Nebula sculpt its ridges and cavities seen in familiar in telescopic images. Similar in size to the Orion Nebula, this Great Turkey Nebula was imagined to be about 13 light-years across. Stay safe and well.

说明: 横跨这幅很有创意视野的火鸡大星云，会让人们联想起猎户大星云。想当然耳，如果它是座落在一个大分子云边缘的猎户大星云，那它离我们仅有1,500光年远，所以是最邻近我们的大恒星形成区。亦名为M42的猎户大星云，在人类的肉眼中，是目前冬季夜空的猎户座内，猎人配剑上的第二颗”星”。而散布在猎户座各处的成团新诞生恒星，所发出的恒星风雕塑出此区望远镜影像里，这些我们很熟悉的云脊和空穴。如果火鸡星云与猎户大星云大小相当的话，那么这只火鸡的身宽有13光年。祝你有个平安快乐的感恩节。 （译注：这则天文图的哏是”感恩节的火鸡”。在美国，2020年的感恩节落在11月26日。）
