8月底以来，就一直传言世界各地70多家天文台早早地准备联手发布重磅炸弹，搞得好多吃瓜群众们既心慌慌又心痒痒的：莫非是外星人真的要来了？积木英语天文望远镜，带你一起去看看这件新鲜事！

现在谜底揭晓：没有大家期待的外星人。北京时间2017年10月16日22:00（美国东部时间10月16日10时），LIGO-Virgo 科学合作组及全球各主要天文台同步发布重大天文学发现：首次直接探测到了由双中子星并合产生的时空涟漪——引力波及其伴随的电磁信号，正式编号——GW170817。

话说啥叫引力波呢？简单的来说，引力波是指时空弯曲中的涟漪，通过波的形式从辐射源向外传播，这种波以引力辐射的形式传输能量。在爱因斯坦的描述中，有质量的物体会使它周围的时空发生扭曲，物体的质量越大，时空就扭曲得越厉害。总之，释放的能量之大超乎你的想象。

这次中子星碰撞产生的引力波对天文学界意义重大，产生的一系列成果就留待科学家们继续研究吧。

是不是觉得懂得这么高深知识的科学家们棒棒的？如果你也想成为科学家为人类和我们的家园造福，需要具备相当程度的科学素养~ 积木英语不仅仅是搭建积木和学习英语，也在这个过程中还培养了小盆友们创造力、动手能力，而这些是叩开科学大门的基础。来到积木英语，对于孩子来说会是一个不错的选择哟~

On October 16, 2017, the LIGO Scientific Collaboration, Virgo Collaboration, and its partners announced the first observation of gravitational-waves-ripples in space-time-  from the spectacular collision of two neutron stars. Electromagnetic emission from the resulting collision was also observed in multiple wavelength bands. This occured on August 17, 2017 and represents the first time a cosmic event was observed with both gravitational waves and light.
