作者：全景再现科技 标题：火焰星云隐藏的火焰

简介： The hidden fires of the Flame Nebula。This image, the first to be released publicly from VISTA, the world’s largest survey telescope, shows the spectacular star-forming region known as the Flame Nebula, or NGC 2024, in the constellation of Orion (the Hunter) and its surroundings. In views of this evocative object in visible light the core of the nebula is completely hidden behind obscuring dust, but in this VISTA view, taken in infrared light, the cluster of very young stars at the object’s heart is revealed. The wide-field VISTA view also includes the glow of the reflection nebula NGC 2023, just below centre, and the ghostly outline of the Horsehead Nebula (Barnard 33) towards the lower right. The bright bluish star towards the right is one of the three bright stars forming the Belt of Orion. The image was created from VISTA images taken through J, H and Ks filters in the near-infrared part of the spectrum. The image shows about half the area of the full VISTA field and is about 40 x 50 arcminutes in extent. The total exposure time was 14 minutes. This image is available as a mounted image in the ESOshop. 这是世界上最大的巡天望远镜VISTA首次公开发布的图像，显示了猎户座及其周围壮观的恒星形成区域，称为火焰星云或NGC 2024。在可见光下观察这一令人印象深刻的天体时，星云的核心完全隐藏在模糊的尘埃后面，但在这张由红外光拍摄的远景图中，揭示了该天体中心非常年轻的恒星团。广角视景还包括中央下方反射星云NGC 2023的辉光，以及右下角马头星云（Barnard 33）的鬼影轮廓。右侧明亮的蓝色恒星是构成猎户座带的三颗明亮恒星之一。这幅图像是从光谱近红外部分通过J、H和Ks滤光片拍摄的VISTA图像创建的。该图像显示了整个VISTA区域的大约一半区域，范围约为40 x 50 arcminutes。总暴露时间为14分钟。此映像在ESOshop中作为挂载映像提供
