in the universe where life exists.
另一顆存在生命的行星。
with my naked eyes
最先進的望遠鏡觀測到這顆行星。

按照某個適當的距離,
圍繞著恆星旋轉的那種行星。
at just the right distance
for stars of different temperatures,
之間的適當距離,
for water to flow on their surfaces
從而能使水源在它們的表面流動起來
and energy on finding planets
便把他們的目光及精力集中在
維持適當距離的行星研究上。
這些天文學家們的研究結果而展開的。
climates of exoplanets.
太陽系以外的行星上可能出現的氣候。
besides distance from its star
一個行星是否能夠維繫生命的存在。
a planet can support life.
的愛神、美神維納斯,

金星另一個不同的故事。

and scorching the planet's surface.
並烘烤著行星表面,
initial perceptions of this planet.
(人們對於金星)最初的認識。
from our own solar system,
and potential to host life.
有著決定性的作用。
of these planets are like
究竟有什麼樣的大氣層。
and dim compared to their stars
這些行星不僅太小還昏暗不清,
that could support surface water --
可能存在地表水的行星,

系外行星而言,
測量它的大氣層成分非常困難。

可能產生出一種適宜的氣候。
for water and life.
可以保證水源和生命的存在。
“卡普勒62F”的一個概念(作品),

could be warm enough for open water
的研究發現這顆行星可能足夠溫暖
從而存在水源,

不同方向的運行軌道的情形下都是這樣。
to follow up on this planet
可以跟蹤這顆行星,
對於氣候也有重要的影響。

正是因為這個原因。

圍繞溫度較冷的恆星旋轉的行星
than planets orbiting hotter stars.
溫度較高的恆星旋轉的行星溫度更高。
wavelength light from cooler stars,
發射出來的波長較長光;
heats the ice.
會使冰本身的溫度升高。
這些矛盾如何影響行星上的氣候
can affect planetary climate
有至關重要的意義。
