非凡的生日照,NASA开放搜索生日当天的宇宙星空照

行动管制期间的寿星们,几乎是独自庆生有别于以往的生日派对与亲朋好友欢聚,美国国家航空航天局(NASA)为即将登上太空服役满30年的哈勃空间望远镜(Hubble Space Telescope)举办一场独一无二的庆生活动,公开366张不同日期的宇宙星空照。

浩瀚又充满许多神秘未解的宇宙,总是吸引着我们地球人的好奇心想要一探究竟,1990年4月24日被发射至外太空中的哈勃空间望远镜,由处于地球大气层之上的绝佳位置,拍摄的的影像可以不受大气端流的扰动、背景光和紫外线等影响,弥补了不少地面观测的缺点,不仅帮助天文学家对宇宙有更深入的研究,也帮助人类更了解未知的宇宙。

#Hubble30 (1994) One of the Hubble Space Telescope's most famous images, these towers of gas and dust in the Eagle Nebula (M16) are known as the "Pillars of Creation." The pillars are in some ways akin to buttes in the desert, where basalt and other dense rock have protected a region from erosion, while the surrounding landscape has been worn away over millennia. In this celestial case, it is especially dense clouds of molecular hydrogen gas and dust that have survived longer than their surroundings in the face of a flood of ultraviolet light from hot, massive newborn stars (located off the top edge of the picture). This process is called "photoevaporation." This ultraviolet light is also responsible for illuminating the convoluted surfaces of the columns and the ghostly streamers of gas boiling away from their surfaces, producing the dramatic visual effects that highlight the three-dimensional nature of the clouds. The tallest pillar (left) is about 4 light-years long from base to tip. As the pillars themselves are slowly eroded away by the ultraviolet light, small globules of even denser gas buried within the pillars are uncovered. Forming inside at least some of the globules are embryonic stars. For more information, follow the link in our bio. Credit: NASA, ESA, STScI, J. Hester and P. Scowen (Arizona State University)
