If this code is sent by aliens, you can crack it? -Aliens, the binary-IT information
On May 6, according to United Kingdom daily mail reports, if the aliens are trying to use the encrypted binary information contact Earth, humans are able to understand the information they convey? Germany marks-astrophysicist leien·Hele of the Max Planck Institute for solar system research (Ren é Heller) developed a test. As part of this project called Seti decryption challenge, scientists released consists of 0 and 1 of a great message, and invited the public to crack it.
"Assuming the telescope on earth outside our solar system is a fixed series of pulses from an unknown source, a computer algorithm identifies the artificial nature of the pulse and found that these pulses contain a message. "The results of this challenge will be announced on June 3.
Crack this password will reveal the alien′s height, they lived, how big is this device that transmitted signals, how long has he sent information in the milky way, he do for a living, and his history of the solar system.
Heller says you can work with anyone, many people already live on Twitter they hack progress label #SetiDecryptChallenge Tweets. Whichever way you hack this information must appear to a human is able to read and understand forms.
Last month, Heller published an article, we have narrowed the scope of the search to those aliens can be seen on our aliens. This study, published in the journal Astrobiology, also includes laerfu·puruizi (Ralph Pudritz) work, which discusses various ways to ensure that the alien will successfully detect life on Earth.
In the search for extraterrestrial life in the process, astrobiologists the most research has focused on those so far unable to use telescopes to planets and moons, so they can only be tracking these objects from the transit of shadows to study them before the host stars. "We are using a method called transit, primarily detect planets passing across the front of the case. ”
"No doubt this is the discovery of a planet and its size is the simplest and most direct methods. "If a planet from its parent stars ahead after, the star′s observed brightness slightly decreased. By measuring the stars when planets transit level, scientists can gather a lot of information, they don′t even need to directly observe the planets.
"Prove that there is life on the planet is a very difficult task, scientists must use the latest telescopes may be completed. However, we can be determined from the Earth-like candidate begin, such as Rocky planets like Earth. ”
In order to identify a potential target, first of all, scientists must understand the planet supports life. "Light of your analysis through the planet′s atmosphere will host stars in order to investigate whether it contains a pattern of molecules associated with life. ”
Helle and Pudritz says we should focus on the transit of the Earth, if aliens exist in this small region, they will be able to see the Earth from the Sun in transit.
The transit of the Earth (ETZ) contains more than 100,000 potential targets, each have habitable planets and moons around, and this value is just that we use radio telescopes can see.
"If you are the observer from ETZ, you can′t see the Earth, ETZ only thousands of light years from Earth. Of course, we cannot predict what other observers can also detect planets has intelligent life, but this search is based on basic physics concepts based on simple and effective methods, so don′t use it is next to impossible. ”
There have been several projects are now in progress, which is sending signals from the Earth, while searching for those that signals sent directly. Heller at Canada′s McMaster University as a postdoctoral fellow in cooperation with Pudritz, two person, so far as part of the search for extraterrestrial life with the most comprehensive investigation, "breakthrough to listen initiatives (Breakthrough Listen Initiative)" by narrowing down the search to the transit zone of the Earth, thereby maximizing the probability of successful searches.

外星人发送，你能破解吗？ -
外星人,二进制 - IT资讯
5月6日消息，据英国每日邮报报道，如果外星人试图利用加密的二进制信息联系地球，人类是否能够理解他们所传达的信息？德国马克斯-普朗克太阳系研究所的天体物理学家雷恩·赫勒（RenéHeller）开发了一个测试。作为这项名为Seti解密挑战的一部分，科学家发布了由0和1组成的一条巨大信息，并邀请公众破解它。
“假设地球上的望远镜接收到太阳系外一个固定未知来源的一系列脉冲，一个计算机算法鉴别了脉冲的人工本质，结果发现这些脉冲包含了一条信息。”这项挑战的结果将在6月3日公布。
破解这一密码将揭示外星人的身高，他们的寿命，这个传输信号的设备有多大，他在银河系内发送信息有多久，他以什么为生，以及他的太阳系的历史。
赫勒表示你可以与任何人合作，很多人已经在推特上直播他们的破解进展，推文标签为#SetiDecryptChallenge。无论你是用什么方法破解这些信息，显示的结果必须是人类可以看懂的形式。
上个月，赫勒发表了一篇文章称，我们已经将外星人搜寻的范围缩小到那些可以看到我们的外星人上。这项发表在期刊《天体生物学》上的研究还包含拉尔夫·普瑞兹（Ralph Pudritz）的工作，后者探讨了确保外星人成功检测地球上生命的各种方法。
在搜寻外星生命的过程中，天体生物学家的大多数研究关注那些太过遥远无法利用望远镜观测到的行星和卫星，所以他们只能通过追踪这些天体从宿主恒星前过境时的阴影来研究它们。“我们使用的是名为过境的方法，主要是检测行星从恒星前方过境时的情形。”
“无疑这是发现一颗行星存在以及它大小的最简单也是最直接的方法。”如果一颗行星从它的母恒星盘前方经过，恒星的可观察到的亮度会略微有所下降。通过测量行星过境时星光黯淡的程度，科学家可以收集到大量信息，他们甚至无需直接观测到这些行星。
“证明一颗行星上存在生命是一项非常困难的任务，科学家们必须借助最新望远镜才可能完成。但是，我们可以从那些被确定类似地球的候选者开始着手，例如类似地球的岩石行星。”
为了鉴别一个潜在目标，首先科学家必须理解这颗行星是否支持生命存在。“你将分析穿过行星大气层的宿主恒星的光，从而调查它是否包含与生命相关的分子的印记。”
赫勒和普瑞兹表示我们应该将搜寻关注于地球的过境区，如果外星人存在这片小区域里，他们将可以看到地球从太阳前方过境。
地球的过境区（ETZ）包含10万多个潜在目标，每一个都有可居住行星和卫星环绕着，而这一数值仅仅是我们利用现在无线电望远镜可以看到的。
“如果你是来自ETZ的观察者，你不可能看不到地球，ETZ距离地球只有几千光年。当然我们无法预测其它地外观察者还可以以什么方式检测拥有智能生命的行星，但这种搜寻程序是利用基于基本物理概念的简单而有效的方法，所以不使用它几乎是不可能的。”
目前已经有好几个项目正在进行中，它们主要是从地球上发送信号，同时搜寻那些直接发送的信号。赫勒在加拿大麦克马斯特大学担任博士后研究员时与普瑞兹合作，两人提出，作为目前为止搜寻外星生命最全面调查的一部分，“突破聆听举措(Breakthrough Listen Initiative)”项目通过将搜寻范围缩小到地球的过境区，从而极大化搜索成功的概率。
