我们太迟了吗?附近的类地行星比邻星b被超级耀斑猛烈撞击可能已经摧毁了外星生命的任何可能性

一份新的报告显示，“类地行星”比邻星b被一种“超级耀斑”所击中，比以往任何时候都要大10倍，这使得在那里生存的生命的机会渺茫。

在2016年被发现，比邻星b围绕着离太阳最近的恒星，比邻星，被天文学家誉为生命形式的合适地点——也许，甚至是未来的人类生活的地方。

在距离地球仅4光年的地方，专家们相信，太空飞船在未来可以探测到它的表面。

然而，北卡罗来那大学教堂山分校的研究人员观察到的巨大的太阳耀斑可能会摧毁地球上的任何生命。

这颗超级耀斑使比邻星的亮度比平时高出68倍，并可能使其轨道近b行星上的任何生命暴露于致命的紫外线辐射水平。

天文学家在周二发表的一篇论文中写道，这是因为“足够明亮和频繁的耀斑和任何相关的质子事件可能会破坏地球的臭氧层，使致命的紫外线通量达到其表面。”

他们补充说，比邻星的“高恒星活动”，如太阳耀斑，“对比邻星b的可居住性产生了怀疑”。

Yes like we really know the answer? living in our own little run around 9 to 5 worlds too busy to understand the nature of reality. Some believe what they are TOLD some don't!

是的，就像我们真的知道答案一样？生活在我们自己的小世界里，忙碌得无法理解现实的本质。有些人相信他们被告知的话，有些人不相信！

The assumption is that life would develop on the surface. Evolution would favour an underground environment, shielded from the radiation.

人们的假设是，生命将在表面上发展。进化将有利于一个地下环境，不受辐射的影响。

So "scientists believe the extreme solar activity will likely reduce the ozone of Proxima b's Earth-like atmosphere by 90% within five years"? We know NOTHING about the atmosphere of Proxima B! It may even not have one! More fake news.

因此，“科学家们相信，极端的太阳活动可能会在五年内将比邻星b类地大气层的臭氧减少90%”？我们对比邻星的大气层一无所知！它甚至可能没有一个真是的新闻！漫天的假新闻。

Missions to send spacecraft to the planet to examine for signs of life are already in planning, and could happen wiithin decades. Save millions of $! You are too late.

派遣宇宙飞船到地球去检查生命迹象的任务已经在计划之中，而且可能会在几十年内发生。拯救数百万美元!你太迟了。

still they can't show a real picture of the ball earth, even nasa admit they are all fake composites, paintings, CGI , no real picture. they can't even show the curvature without faking it with fisheye lenses

尽管如此，他们还是不能展示真实的地球，甚至nasa也承认它们都是假的合成物，绘画，CGI，没有真实的图片。他们甚至不能在不使用鱼眼镜片的情况下显示曲率

Observing the result of 'life' here on this little rock perhaps we should all be grateful the distances between life forms are so vast we will almost certainly never meet any of them.

观察这个小岩石上的“生命”的结果，也许我们都应该感谢生命形式之间的距离如此之大，我们几乎肯定不会遇到它们中的任何一个。

To Old world order. Before science we had no idea how immense the universe was and how astonishing its properties. Therefore by your reckoning, God loves us doing astronomy.

旧世界秩序。在科学之前，我们不知道宇宙有多么巨大，它的特性有多惊人。因此，根据你的估计，上帝爱我们做天文学。

The places in the universe where life has any chance at all are few and far between. And to get something as magnificent as Earth requires the help from aliens as well.

在宇宙中，生命有任何机会的地方很少，而且相隔甚远。要得到像地球一样壮丽的东西，也需要外星人的帮助。

Too late? Not likely. It isn't likely this is Proxima Centauri's first major flare in billions of years. The planet almost certainly has been blasted many, many times before.

太晚了吗?不太可能。这不大可能是半人马座阿尔法星在数十亿年里的第一次大耀斑。这颗行星几乎肯定已经被炸过很多次了。

Research also tells me that 18 beers a night is too many and that research is wrong so I assume that this research is also wrong.

研究还告诉我，每晚18瓶啤酒太多，研究是错误的，所以我认为这项研究也是错误的。

Proximal b might have a magnetic field strong enough to shield the planet from the superflare

比邻星b可能有一个足够强大的磁场来保护地球免受超级耀斑的影响

Petpac93, Theath, United Kingdom, 1 day ago

Oh, yeah, meaning that the radiation, if any, came in 2016, ie 2 years ago and we seem to gave survived.

哦，是的，这意味着辐射，如果有的话，是在2016年，也就是2年前，我们似乎幸存了下来。

We are significantly further away though....

我们离得很远。

If Proxima b is 4 light years from Earth that means that four years after the flare some of that radiation will be arriving here...I wouldn't worry to much though, the Inverse Square law comes into effect...the power of the flare will diminish over the square of the distance...phew...

如果比邻星b距离地球4光年这意味着在耀斑爆发4年后，一些辐射将会到达这里。我不太担心，平方反比定律开始生效。耀斑的力量会减弱到距离的平方。

We're not goinig to find life around red dwarfs, their water zone is also their nucIear reactor zone. The way to find what's most likely primordial life is to search for the flukes that make us Earth - the simplets being small inner plannets surrounded by multiple distant gas giants that shield them (a situation which Kepler currently hasn't found anywhere else in the galaxy).

我们不可能在红矮星周围找到生命，他们的水域也是他们的核反应堆区。寻找最可能的原始生命的方法是寻找使我们地球成为地球的河流——这些小的是小的内网，被许多遥远的气态巨行星包围着，它们保护着它们（这是开普勒目前在银河系中没有发现的情况）。

We should considering the idea that on other planets there might be silicon rather than carbon based life which means they would not need water.

我们应该考虑这样一种观点，即在其他星球上可能存在硅而不是基于碳的生命，这意味着它们不需要水。
