GJ 581d被认为是在太阳系之外宜居带内发现的绕恒星运动的第一颗行星。宜居带不冷不热,适合生命生存。
To find Gliese 581d, University of California, Santa Cruz astronomers originally looked for subtle changes in light caused by the gravity of an orbiting planet tugging back and forth on the star.
为寻找Gliese 581d,加利福尼亚大学的圣克鲁斯天文学家们最初发现了由绕恒星运行的行星来回摆动造成的光变化。
The strength of the tugging, they believed, showed them a planet was about three times as massive as Earth.
他们认为这种摆动的强度表示这颗行星的体积是地球的三倍。
At the time, the discovery of Earth-like planets around Gliese 581 caught the public imagination.
绕Gliese 581运行的类地行星发现之后,激发了公众的想象力。
Documentary-maker RDF and social-networking site Bebo used a radio telescope in Ukraine to send a powerful focused beam of information - 500 messages from the public in the form of radio waves - to Gliese 581.
英国RDF电视传媒和社交网站Bebo使用乌克兰的无线电天文望远镜将以无线电方式收集的500条来自大众的信息发送了给了Gliese 581。
And the Australian science minister at the time organised 20,000 users of Twitter to send messages towards the distant solar system in the wake of the discoveries.
