It came from the direction of Sagittarius; the nearest star in that direction is 220 light-years away.
它来自射手座的方向;那个方向最近的恒星距离220光年。
So, I think we'll be able to do to a lot better than 2,000 years to the nearest star.
因此我认为我们可以做到在远小于2000年的时间内抵达最近的恒星。
Measuring the distance to the nearest star, on the other hand, can be a little tricky.
另一方面,要测量与最近恒星间的距离可能有些棘手了。
Of course, that also means the craft would require 7,000 years to reach the nearest star — but that's if the sails depended on current technology.
当然即使如此,这也意味着飞船需要7000年才能抵达最近的恒星,但要注意的是,这种假设是基于目前的技术而言的。
Fair question. After all, if we can detect gravitational waves, or send a probe to land on a comet, surely we can send some rubbish to our nearest star?
这是个不错的问题。毕竟,如果我们能探测到引力波,能发送探测器到彗星上,那我们为什么就不能将垃圾送到离我们最近的星球上去呢?
We see the moon as it was 1.3 seconds ago; the sun as it was 8.3 minutes ago; the nearest star 4.2 years ago; the most distant galaxy as it was about 13.3 billion years ago.
我们看到的月亮,是1.3秒以前的;太阳,是8.3分钟以前的;离地球最近的星星,是4.2年以前的;而离地球最远的星系,则是133亿年前的。
Those are amazing objects in their own right, and also rather rare (perhaps because they're so difficult to spot) : there's eight known white dwarfs in the hundred nearest star systems to our sun.
白矮星是具个性的,也是非常稀有(可能因为定位它们很困难)令人惊异的恒星,在上百个离我们的太阳最近的星系中只有八颗已知的白矮星。
A fourth object, which has more than ten times the mass of Earth and is the nearest to the star yet found, was noticed by another team in 2004.
第四颗行星被另一个科研小组于2004年发现,它有着地球十倍的质量,而且是与那颗已知恒星距离最近的。
