According to foreign media reports, the Arecibo Observatory in the United States has the world's largest single-aperture radio telescope, which has played a huge role in the field of scientific research, but in recent years it has fallen into financial difficulties, and has had to suspend many research projects, and may even completely shut down the radio telescope.

1. The glorious history of the Arecibo radio telescope.
The reason why the radio telescope of the Arecibo Observatory is so remarkable is that it is the largest single-aperture radio telescope in the world, this radio telescope was built in 1988, the radio telescope is characterized by being able to receive radio waves in the universe, it was also built to better observe the stars in the universe, and the radio telescope can also play the function of radar, because it has the function of actively emitting signals.

In 2005, the Arecibo telescope used its radar function to carry out high-resolution imaging of the surface of the asteroid, which was also the first high-resolution imaging of the surface of the asteroid in human history, and in the process of imaging, the Arecibo telescope also found many characteristics of radio waves, which also gave researchers a deeper understanding of radio waves in the universe.
In 2006, the Arecibo telescope also discovered the planetary system outside the solar system, which is also the first time in human history to discover the planetary system outside the solar system, it can be said that the establishment and use of the Arecibo telescope has brought great progress to the field of human scientific research.

The construction and operation of the Arecibo telescope requires continuous financial support, and in recent years, scientific research funding in the United States has been decreasing year by year, which has also put the maintenance of the Arecibo telescope in a difficult situation, and also led to the equipment on the Arecibo telescope falling into disrepair, and the function of many devices has gradually declined over time.
In recent years, the Arecibo telescope has also discovered many major astronomical phenomena, such as gravitational waves discovered in 2017, but with the reduction of funding, the Arecibo telescope has had to suspend many research projects, and may even shut down the radio telescope completely.
Second, FAST will also face the fate of retreat in the future.
The decline of the Arecibo telescope has made many netizens feel very bitter, and they are worried about whether China's FAST will experience the same fate as the Arecibo telescope in the future, after all, FAST also needs long-term financial support, and it also needs careful maintenance by scientific researchers, but for a long time, FAST has not received enough maintenance funds.
According to reports, within a year of its completion, FAST used up five years of maintenance funds ahead of schedule, and due to the lack of maintenance funds, many of the equipment on FAST could not be used normally, and even some of the core equipment was in a semi-damaged state.

Moreover, after the completion of FAST, it also faced many problems, such as the surrounding residents will interfere with FAST, and some residents have even built hotels and other facilities in the surrounding area, which has greatly affected the operation of FAST, and at the same time, the surrounding facilities have also interfered with FAST.
In order to protect the normal operation of FAST, Chinese researchers had to demolish the surrounding facilities, but in the process of demolition, Chinese researchers were also disgusted by some residents, and some residents even refused to move out, which also caused great difficulties in the maintenance of FAST's equipment.

At the same time, the operation and maintenance of FAST also requires a lot of manpower, China's FAST after the completion of the large, attracted a large number of scientific researchers to come to study, but in so many scientific researchers, there is no one specifically responsible for the maintenance of FAST personnel, which also makes the maintenance of FAST fall into an embarrassing situation, it is reported that after the completion of FAST, it has attracted a large number of researchers to come to study, but only a dozen maintenance personnel.
In the process of maintenance, some researchers will also cause some damage to the equipment on FAST, which also makes FAST maintenance personnel busy with maintenance and complaints.
Third, the decline of scientific research facilities should be paid attention to.
The decline of the Arecibo telescope and whether FAST will face the fate of closure in the future have caused many netizens to worry, and they are all saddened while calling on the government to provide more funding for scientific researchers, and at the same time to carry out stricter management of scientific research facilities, and not to abandon important scientific research facilities because of funding problems.

Scientific research is international cooperation, and the scientific research facilities of different countries can complement and cooperate with each other to jointly promote scientific progress, so the funds on scientific research facilities cannot be saved, and the forgetting and decline of scientific research facilities will have a negative impact on the progress of scientific research.
Scientific research institutions and the government should also make more reasonable arrangements for the construction and maintenance of scientific research facilities, otherwise there will be progress in the construction of new facilities on the one hand, and difficulties in maintaining old facilities on the other, which will lead to many scientific research facilities being abandoned because of funding problems, and this result is not conducive to the progress of national scientific research.
