天文学家利用NASA的哈勃空间望远镜编辑出了一个关于在宇宙遥远处的引力透镜的巨大目录。这个目录包括了67个新的引力透镜星系图片,在其周围拥有大量的椭圆状星系和透镜状的星系。这些例子指明了强大的引力透镜富含多样性。假如这些例子都是典型的,那么在整个宇宙空间中必定存在着将近50万左右的引力透镜。宇宙工程,由来自加利福尼亚技术研究所的Nick Scoville所主持,他利用一些天文台的观测结果,其中包括哈勃,斯必泽空间望远镜,XMM牛顿宇宙飞船,钱德拉X射线天文台,巨大的望远镜和Subaru望远镜。一个欧洲天文组织,由Cecile Faure (天文学,海得堡大学)和Jean-Paul Kneib (Laboratoire d'Astrophysique de Marseille) 共同主持,他们利用3个关键的宇宙测量数据集:先进的哈勃高分辨率测量成相仪,Subaru望远镜上的Suprime成相仪和加拿大-法国-夏威夷望远镜上的多色成相仪
Astronomers using NASA's Hubble Space Telescope have compiled a large catalog of gravitational lenses in the distant universe. The catalog contains 67 new gravitationally lensed galaxy images found around massive elliptical and lenticular-shaped galaxies. This sample demonstrates the rich diversity of strong gravitational lenses. If this sample is representative, there would be nearly half a million similar gravitational lenses over the whole sky. The COSMOS project, led by Nick Scoville at the California Institute of Technology, used observations from several observatories including Hubble, the Spitzer Space Telescope, the XMM-Newton spacecraft, the Chandra X-ray Observatory, the Very Large Telescope, and the Subaru Telescope. A team of European astronomers, led by Cecile Faure (Zentrum fur Astronomie, University of Heidelberg) and Jean-Paul Kneib (Laboratoire d'Astrophysique de Marseille) utilized three key data sets of the COSMOS survey: the Hubble Advanced Camera for Surveys high resolution imaging, the Suprime camera Subaru Telescope imaging, and the Megacam camera Canada-France-Hawaii Telescope multicolor imaging.
