NGC 2170: Angel Nebula Abstract Art

Explanation: Is this a painting or a photograph? In this celestial abstract art composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines just above the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars. Like the common household items that abstract painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in a setting like this one — a massive, star-forming molecular cloud in the constellation of the Unicorn (Monoceros). The giant molecular cloud, Mon R2, is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be over 60 light-years across.

说明: 这是画还是照片呢？在这辐用宇宙画笔绘就的天体抽象画里，名为天使星云的尘埃云NGC 2170，于影像的中上方绽放光芒。因反射邻近炽热恒星的星光而现踪的NGC 2170，附近还有其他的泛蓝反射星云、泛红小发射星云、数量众多的黝黑暗星云、和色彩缤纷的背景恒星为伴。就像抽象画家经常以居家的物品为题材一样，在麒麟座（独角兽）的这团大质量恒星诞生云之内，云气、尘埃和炽热恒星也是随处可见。这团名为Mon R2的巨分子云，离我们非常近，其距离估计在2,400光年左右。以此距离来换算，这幅”画布“的宽度超过60光年。
