The definition of “habitable zone” is the distance from a star at which liquid water could exist on orbiting planets' surfaces.

This newly discovered exoplanet is in its star's habitable zone and is the closest to Earth in size and temperature found yet in Kepler's data.
NASA (.gov)
One required ingredient for habitability is liquid water, so the planet must orbit in the region around its star where liquid water can exist ...

原文摘录:The definition of “habitable zone” is the distance from a star at which liquid water could exist on orbiting planets’ surfaces. Habitable zones are also known as Goldilocks’ zones, where conditions might be just right – neither too hot nor too cold – for life.

虽然文章提到Kepler-452b位于宜居带内已有60亿年,这为生命可能出现提供了"充分机会"(substantial opportunity),但NASA的科学家仅表示这是一种可能性,前提是"如果所有必要的成分和条件存在于这个行星上"(should all the necessary ingredients and conditions for life exist on this planet)。
Jon Jenkins(NASA艾姆斯研究中心开普勒数据分析负责人)的陈述表明,科学家们认为这颗行星在宜居带内存在的时间比地球还长,理论上有足够的时间让生命出现,但这只是一种推测,而非确认发现生命或生态系统的证据。

We need only detect the telltale signs of life in an exoplanet atmosphere, and we have a better understanding of what those look like here on Earth.

A habitable planet is one that can sustain life for a significant period; based on our solar system, life requires liquid water, energy, and nutrients.

Habitable zones potentially capable of hosting life-bearing planets are wider for hotter stars. Smaller, dimmer red dwarfs, the most common type in our Milky ...
