很少有宇宙景观能像猎户座大星云那样激发人们的想象力。这张清晰的望远镜照片拍摄于1月一个寒冷的夜晚,地点是地球西弗吉尼亚州,拍摄地点是黑暗的天空。猎户座星云也被称为M42,它的发光气体围绕着炙热的年轻恒星。它直径约40光年,位于一个巨大的星际分子云的边缘,距离我们只有1500光年,与太阳位于银河系的同一螺旋臂内。除了尘封的蓝色反射星云NGC 1977和画面顶部附近的朋友外,这个引人注目的星云只代表了我们银河系附近丰富的恒星形成物质的一小部分。在这个被充分研究过的恒星摇篮里,天文学家还发现了许多似乎是婴儿太阳系的东西。

Few cosmic vistas excite the imagination like The Great Nebula in Orion. Visible as a faint celestial smudge to the naked-eye, the nearest large star-forming region sprawls across this sharp telescopic image, recorded on a cold January night in dark skies from West Virginia, planet Earth. Also known as M42, the Orion Nebula's glowing gas surrounds hot, young stars. About 40 light-years across, it lies at the edge of an immense interstellar molecular cloud only 1,500 light-years away within the same spiral arm of our Milky Way galaxy as the Sun. Along with dusty bluish reflection nebula NGC 1977 and friends near the top of the frame, the eye-catching nebulae represent only a small fraction of our galactic neighborhood's wealth of star-forming material. Within the well-studied stellar nursery, astronomers have also identified what appear to be numerous infant solar systems.
