Not a drill演习，（fire drill,消防演习，这次来真的）: SETI(是一个组织，通过各种设备检测能否找到外星的信号，还有seti at home个人电脑处理器加入监测）is investigating a possible extraterestrial Signal from Deep Space.
An international team of scientists from the Search for Extraterrestrial地球以外的 Intelligence (SETI) is investigating mysterious signal spikes （很大很突然的一个信号） emitting from a 6.3-billion-year-old 63亿 star in the constellation星座 Hercules—95 light years away from Earth. The implications 意味are extraordinary非同寻常 and point to the possibility of a civilization far more advanced than our own. 第一句第一段要读清楚。
The unusual signal was originally detected 被监测到on May 15, 2015, by the Russian Academy of Science-operated RATAN-600 radio telescope in Zelenchukskaya, Russia, but was kept secret from the international community. Interstellar 星际的space reporter Paul Gilster broke the story透露，破案了 after the researchers quietly circulated a paper announcing the detection of “a strong signal in the direction of HD164595.” 地名，人名，名称d不用在意。

So far, a single Neptune-like海王星 (but warmer) planet has been discovered in its orbit—HD 164595 b. But as Gilster explained, “There could, of course, be other planets still undetected in this system.”
Decorated 荣誉的Italian SETI researcher and mathematician Claudio Maccone along with Russia’s Nikolai Bursov of the Special Astrophysical Observatory are the principal 主要的scientists working on the apparent看上去的 discovery. They claim that “permanent monitoring 永久of this target is needed.” 哪些人在做。
the signal's strength indicates that if it in fact came from a isotropic 各向同性beacon, the power source would have to be built by a Kardashev Type II civilization. the kardashev scale is used to determine the progress of a civilazation's technological development by measuring how myuch energy was used to transmit an interstellar message. an isotropic beacon无线电信标，一直在发信号 means a communication source emtting a signal with equal power in all directions while promoting signal strength throughout travel. 建议去wikipedia网站搜索，卡尔达肖夫指数：根据一个文明所能够利用的能量量级，来h量度文明程度。
In his acclaimed work transmission of information by extraterrestrial civilizations, soviet astronomer Nikolai Kardashev explained that a type II civilization would be able to harness the energy of their entire host star. the most common hypothetical example of this would be a dyson sphere which is a massive artificial structure that could completely encapsulate a star and tranfer the energy to a nearby planet 人造的建筑把一个星球产生的能量发送到旁边的星球。
Basically, if the signal was beamed out into the galaxy without aim or direction, what would require an enormous amount of power to actually be detected. But what is the signal was beamed specifically at our solar system? well, that would require less energy and could indicate意味着 the presence of a kardashv type i civilization meaning that it could be a highly technological, contemporary society that harnesses the solar energy emitted by its local star, much like our planet does with solar panels, this particular civilization 's social structure is theorized理论上 to be completely globalized and interconnected.不一定是type2，也许是type1，只需要一部分能量发给我们d太阳系。也是一个全球化的社会，
The signal is provocative非常有争议，引人思考 enough that the researchers are calling for permanent monitoring of this target, said gilster, and that is exactly what is transpiring. as of last night, the seti institure is diverting 转移its allen telescope 望远镜array in northern california to investigate while their counterparts职位相关 at meti international messaging 发射信号extraterestrial intelligence will use panama's boquete optical observatory.
The detection of the mysterious signal and the ensuing investigations will be discussed at the IAA SETI Permanent commitee during the 67th international astronautical congress in guadolajoara, mexico, on SEP. 27, the same day and location where elon musk will reveal his plans to colonize mars, the observer will be following up on both these stories from the congress.
