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
