从这些数据中，他们设定了一个称为“可居住度”的值，代表一颗行星的温度和质量，决定了它是否能支持生命的存在。
From that data, they've devised what they term the "habitability metric," a value representing a planet's temperature and mass that determines whether or not it can support life.

“这代表开普勒团队向实现其目标迈出了重要一步，他们的目标是确定在类太阳恒星周围的可居住地带出现地球大小的行星的频率，”霍尔曼博士说。
"This represents a significant step toward Kepler's goal of determining the frequency of Earth-size planets in the habitable zones of Sun-like stars," Dr. Holman said.
它的运行轨道为近似的圆形，以229天为周期，围绕着两个恒星作轨道运行，这个行星位于这个系统的可居住区之外——所谓可居住区，那里有液体水，正像我们所知道的那样，那里可能会有生命的存在。
Traveling on a nearly circular, 229-day orbit around both host stars, the planet lies outside the system's habitable zone—the region where liquid water, and thus life as we know it, could exist.
这“第一颗可居住的太阳系外行星”的发现史可谓一波三折。
The “first habitable exoplanet” already has a checkered history.
一些批评家们觉得，Traub的“可居住区”太过笼统，还包括了被结冰的二氧化碳云层笼罩的行星。
Some commenters felt that Traub's 'habitable zones' were too generous, it included planets shrouded in icy clouds of carbon dioxide.

太阳系外行星搜索者宣布发现了一个新行星，环绕其遥远恒星的可居住带运行，这一区域既不太热，也不太冷地区有稳定的液态水，有可能成为生命的一个立足之地。
Exoplanet hunters announced a new world orbiting in its dim star's habitable zone, the not-too-hot, not-too-cold region where liquid water is stable and life could potentially find a foothold.
