直接节录目前重点
Today we're announcing the discovery of an exoplanet that as far as we can
tell is a pretty close cousin of Earth. It's the closest so far." "It's Earth
2.0."
我们发现跟地球极为相近的星球，它是地球"2.0"
Today, we're pleased to announce Kepler 452B."
今天，我们宣布这颗星球是Kepler 452B
Kepler 452B is 1.5 times the size of Earth - so it's likely to be rocky. It's
also the right distance from its star to potentially be inhabitable.
Kepler 452B是地球的1.5倍大，而且有类似像是岩石，恒星与他的距离
看起来是可以适合居住的
The size of the new planet's orbit is similar to Earth's, and its solar
system is very similar to our own.
轨迹跟地球非常相似，而且它的太阳系也跟我们很像
Kepler 452B is 6 billion years old, and it receives 10 per cent more energy
from its star than Earth
Kepler 452B有60亿岁了，恒星能量对于地球约大于10%
Kepler 452B is 1400 light years from us, orbits its star every 385 days.
它距离我们1400光年，一年有385天
一位老兄在推特说了:
If my math is correct (probably isn't) - it took 9 years to get to Pluto,
which means it would take 550M years to get to Kepler452b. #Kepler
假如我数学没错，到冥王星要9年，那到Kepler452b要5.5亿年
Now, we know of 12 planets that have potentially inhabitable conditions.
我们知道有12颗星球可能具有可以居住的条件
Kepler could also have liquid water, active volcanoes and photosynthesising
plants on its surface.
Kepler可能有液态水、火山和植物
Finally, the million-dollar question - could we travel to Kepler 542B?
最后，我们可以去Kepler 542B旅行吗??
Jeff Coughlin: "This is humankind's first step."
"You and I probably won't be travelling to these planets - but our children's
children's children could be. This gives us something to aim for."
"One generation from now we might be able to get there. It gives humanity
something to aim for."
Jeff Coughlin: 这是人类的第一步，你跟我都不可能去这颗星球的，这些是未来人类们
可以研究的一个目标
我是看文字转播大概翻译一下，反正就是找到跟地球类似的星球了，现场是Q&A时间
小弟要去睡了，应该就这样了，有后续消息，再麻烦其他大大了
