据报道，美国宇航局(NASA)将于北京时间24日零点举办媒体电话会议，发布开普勒太空望远镜的一项新发现，并暗示这将是一个重大消息：宇航员可能发现了人类几千年来梦寐以求的“另一颗地球”。
开普勒太空望远镜自2009年发射升空以来,致力于在“宜居带”寻找类地行星,目前它已发现1000余颗类地行星和3000余颗行星候选者。
但是,NASA暗示,最新发现的也许是目前为止与地球最为相似的一颗。
Kepler Discoveries Update
Noon EDT, Thursday July 23
The first exoPLAnet orbiting another star like our sun was discovered in 1995. Exoplanets, especially small Earth-size worlds, belonged within the realm of science fiction just 21 years ago. Today, and thousands of discoveries later, astronomers are on the cusp of finding something people have dreamed about for thousands of years -- another Earth.
The briefing participants are:
John Grunsfeld, associate administrator for NASA's Science Mission Directorate in Washington
Jon Jenkins, Kepler data analysis lead at NASA's Ames Research Center in Moffett Field, California
Jeff Coughlin, Kepler research scientist at SETI Institute in Mountain View, California
Didier Queloz, professor of astrophysics at Cambridge University, United Kingdom
