特色图片显示了出现在大麦哲伦星云中的暗星云 N11——我们银河系的卫星星系。请参阅说明以获取更多详细信息。

N11: Star Clouds of the LMC

Explanation: Massive stars, abrasive winds, mountains of dust, and energetic light sculpt one of the largest and most picturesque regions of star formation in the Local Group of Galaxies. Known as N11, the region is visible on the upper right of many images of its home galaxy, the Milky Way neighbor known as the Large Magellanic Cloud (LMC). The featured image was taken for scientific purposes by the Hubble Space Telescope and reprocessed for artistry. Although the section imaged above is known as NGC 1763, the entire N11 emission nebula is second in LMC size only to the Tarantula Nebula. Compact globules of dark dust housing emerging young stars are also visible around the image. A recent study of variable stars in the LMC with Hubble has helped to recalibrate the distance scale of the observable universe, but resulted in a slightly different scale than found using the pervasive cosmic microwave background.

N11:大麦哲伦星系的星云

说明: 大质量恒星、高侵蚀性的恒星风、堆积如山的尘埃与及高能量的星光,共同塑造出我们本星系群内,最大最美丽的恒星形成区之一。这个名为的N11的区域,出现在许多以它母星系─我们银河系近邻的影像之右上角。这幅主题影像是由哈勃太空望远镜所拍摄,拍摄的目的原先是为了科学研究之用,后来经过一位业余天文爱好者重新处理以强调其艺术性。虽然影像呈现的天体是NGC 1763,但是更大范围名为N11的发射星云,在大麦哲伦星系里的大小仅次于蜘蛛星云。在这张影像里,到处可见到内部所藏的年轻恒星即将现踪之紧实黝黑尘埃球。最近使用哈勃望远镜针对大麦哲伦星系变星进行的一项研究,重新校准了可见宇宙的距离尺标,而其的结果和使用无比不在的宇宙微波背景测得之尺标有微小的差异。
