We present here an overview of the Hubble Space Telescope ( HST ) program to observe periodic comet 9P/Tempel 1 in conjunction with NASA 's Deep Impact mission. Our objectives were to study the generation and evolution of the coma resulting from the impact and to obtain wide-band images of...
哈勃空间望远镜(Hubble Space Telescope)于1990年4月24日发射升空，它每周7 天、每天24小时地探索宇宙。这意味着它在一年中的每一天都能观察宇宙。NASA由此推出一个名叫"What Did Hubble See on Your Birthday?"的网页，只要输入出生日期，就可以得到一张哈勃空间望远镜在当天拍到的照片（以下照片可以点击大图查看星...

We have presented an overview of the visible imaging obtained with the Advanced Camera for Surveys High Resolution Channel on the Hubble Space Telescope before, during and following the encounter of the Deep Impact spacecraft with Comet 9P/Tempel 1. In addition, we serendipitously observed a natura...
The three-dimensional map of more than 1.1 × 104 galaxies within a sphere of diameter 400 Mpc centered on the Milky Way, created by Huchra and Geller on the basis of more than 5 years' data gathered with an earth-bound telescope comparable in aperture to the Hubble Space Telescope (HST ...
This work summarizes the Hubble Space Telescope nickel-hydrogen (NiH/sub 2/) battery capacity performance from launch to the present time. Over the life of HST vehicle configuration, equipment degradation and equipment failures have had a significant effect on the capacity of the HST batteries. Cha...
