Saturn 1, taken on Hubble's eighth birthday in 1998


(哈勃望远镜在98年第八个生日时拍摄的土星照片) 


Scientists have been paying tribute to the Hubble telescope, 10 years after it was launched.


The Challenger space shuttle carried the US-European space telescope into orbit on 24 April 1990, opening a new era in the history of astronomy.


David Leckrone, a scientist at Nasa's Goddard Space Flight Center in Greenbelt, Maryland, said.


"Not since Galileo aimed a small 30-power telescope into the night sky in 1609 has humanity's vision of the universe been so revolutionised in such a short time span by a single instrument."


世界各地的科学家们为哈勃望远镜庆祝十周岁生日。


1990年的4月24日,挑战者号航天飞机将欧美合作制造的哈勃望远镜送入太空,从而宣告了天文学新时代的到来。


“自从1609年伽利略将他的30厘米望远镜指向夜空起,还没有任何工具在如此短期内给人类的视野带来如此重大的变革。”


美国航空航天局马里兰Goddard空间飞行中心的科学家David Leckrone说
