NGC 2170: Angel Nebula Still Life

Explanation: Is this a painting or a photograph? In this classic celestial still life composed with a cosmic brush, dusty nebula NGC 2170, also known as the Angel Nebula, shines near 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 still life painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in this setting -- 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:这是一幅画还是一张照片?在这幅由宇宙画笔所描绘的经典天体静物画中,亦称为天使星云的尘埃星云NGC 2170在影像中心附近闪耀。NGC 2170因反射附近炽热恒星的星光而发光。影像中还可见其他蓝色反射星云、红色发射星云、许多暗吸收星云以及多彩的背景恒星。就像静物画家经常选择普通家居用品作为题材一样,该特征影像中的气体云、尘埃和炽热恒星也经常出现在麒麟座内的大质量恒星形成分子云中。巨大的分子云Mon R2距离我们非常近,估计只有2400光年左右。以这个距离来计算,这幅画布的宽度将超过60光年。
