仪器接收平台坍塌后的阿雷西博望远镜
据英国广播公司（BBC）报道2日报道称，美国国家科学基金会在周二正式声明，在1日位于波多黎各的阿雷西博天文望远镜塌了。在坍塌之前该望远镜就发生了两起严重的电缆断裂事故，这次重达900吨的仪器平台直接掉到下方的反射盘上，并且再也不能使用，结束了数十年的天文发现之旅。
事实上，阿雷西博天文台是世界最著名的天文台之一，在中国500米口径球面射电望远镜（FAST）出现之前，他曾是全世界最大的单孔径望远镜，在电波天文学、大气科学和雷达天文学等领域贡献巨大。值得注意的是，它还曾向距离地球25000光年的球状星团M13发送了一串信号，包括人类DNA的化学元素序号和结构、人类外形和太阳系信息等。现在看来幸好能量太微弱，没有恒星级的发射功率，不容易被接收。

“阿雷西博信息”
据悉，阿雷西博望远镜的保养费用非常高，经常备受质疑。其实在8月的时候，一根支撑钢缆断裂，就在望远镜的反射盘上砸出一个30米的大洞；在11月初，一个重达16吨的支撑钢缆又断裂，损害了天线。结构非常脆弱，根本无法再维修只能报废。
长期在阿雷西博天文台工作的亚伯·门德斯表示，当知道这一消息时整个人都崩溃了，就像失去生命中一个重要的人。他还提到，阿雷西博和中国的FAST望远镜被誉为地球射电天文学上的“两只大眼睛”。现在能做地外生命探索项目的类似研究的只剩下中国的FAST，而且它还比阿雷西博更灵敏，如果失去阿雷西博就意味着失去24小时监控微弱无线电信号的能力，现在我们只有一只眼睛了。

在事故发生前，世界各地有250名科学家利用这座望远镜开展研究。现在全世界天文探索领域的科研人员和项目，将只能依靠中国的“天眼”，而美国的外星无线电监听计划实质上已经终止。
中国南京大学天文与空间科学学院教授黄永锋表示，这对FAST也提了个醒，而且FAST口径比他更大，我们需要提前做一些预防性设计或者考虑。尤其是后期阶段，望远镜平台安全性、整体运行功能如何保障等问题都是给我们提了醒。

中国天眼
有意思的是，在这次事件后有网友纷纷@赵立坚。因为就在前不久，“五眼联盟”美国、澳大利亚、加拿大、新西兰和英国再次发表联合声明干涉我国内政，对此中国外交部发言人赵立坚表示，不管他们长五只眼还是十只眼，只要胆敢损害中国主权、安全和发展利益，小心他们的眼睛被戳瞎。难道接棒了局座的“因果律武器”？

Overnight, the American Arecibo telescope collapsed. US experts: now we can only rely on China

Arecibo telescope after the instrument receiving platform collapsed
According to a report by the British Broadcasting Corporation (BBC) on the 2nd, the National Science Foundation officially announced on Tuesday that the Arecibo telescope in Puerto Rico collapsed on the 1st. Before the telescope collapsed, two serious cable ruptures occurred. This time, the 900-ton instrument platform fell directly on the reflector below and could no longer be used, ending decades of astronomical discovery. .
In fact, the Arecibo Observatory is one of the most famous observatories in the world. Before the emergence of the 500-meter spherical radio telescope (FAST) in China, he was the world’s largest single-aperture telescope. It has expertise in radio astronomy, atmospheric science, and radar. Great contributions in fields such as astronomy. It is worth noting that it also sent a string of signals to the globular cluster M13, which is 25,000 light-years away from Earth, including the chemical element numbers and structures of human DNA, human appearance and solar system information. Fortunately, it seems that the energy is too weak, and it is not easy to receive without the transmission power of a constant star.

"Arecibo Information"
It is reported that the maintenance cost of the Arecibo telescope is very high and is often questioned. In fact, in August, a support cable broke, and a 30-meter hole was punched in the reflector of the telescope; in early November, a support cable weighing 16 tons broke again, damaging the antenna. The structure is very fragile and cannot be repaired at all and can only be scrapped.
Abel Mendes, who has worked at the Arecibo Observatory for a long time, said that when he learned the news, the whole person collapsed, like losing an important person in his life. He also mentioned that Arecibo and China's FAST telescope are known as the "two big eyes" in Earth's radio astronomy. Now, only FAST in China can do similar research on extraterrestrial life exploration projects, and it is more sensitive than Arecibo. If you lose Arecibo, you will lose the ability to monitor weak radio signals for 24 hours. We only have one eye.

Before the accident, 250 scientists around the world used this telescope to conduct research. Nowadays, researchers and projects in the field of astronomical exploration all over the world can only rely on China’s “sky eye”, and the US’s alien radio monitoring program has essentially ceased.
Huang Yongfeng, a professor at the School of Astronomy and Space Sciences at Nanjing University in China, said that this is also a reminder of FAST, and the caliber of FAST is larger than him. We need to do some preventive design or consideration in advance. Especially in the later stages, issues such as the safety of the telescope platform and how to ensure the overall operating functions have all reminded us.

Chinese Sky Eye
Interestingly, after this incident, some netizens have @赵立坚. Because not long ago, the "Five Eyes Alliance" the United States, Australia, Canada, New Zealand and the United Kingdom once again issued a joint statement to interfere in our internal affairs. In this regard, Chinese Foreign Ministry spokesperson Zhao Lijian said that whether they have five or ten eyes, as long as Dare to harm China's sovereignty, security, and development interests, and be careful of being blinded. Did it take over the "causal law weapon" of the bureau?
