According to an article by the media outlet Revista Economía, Brazil and the People's Republic of China launched a joint scientific project for the construction of a radio telescope that will be used to study dark matter in Latin America.

The radio telescope will be named BINGO, based on the English acronym for BAO from Integrated Neutral Gas Observations, and will be a large-scale infrastructure aimed at investigating, analyzing, and studying one of the most important components of the universe: dark matter.

Once completed, the radio telescope will be located in the Brazilian region of Paraíba, and the project will be carried out by the National Institute for Space Research of Brazil (INPE) and China Electronics Technology Group Corporation (CETC).

This joint project is part of a scientific cooperation agreement between the two nations, and it is expected to be the precursor to future projects in this sector undertaken by both countries.

The project's size is comparable to that of Brazil’s Maracanã Stadium and will make use of advanced technology capable of detecting electromagnetic radiation signals in the radio band. 

The purpose of this joint project between the two nations is to locate, detect, and identify baryon acoustic oscillations, which are a key phenomenon for understanding the distribution of dark matter throughout the universe.

According to reports from the United States' National Aeronautics and Space Administration (NASA), dark matter makes up about 68% of the total universe; however, it has not yet been directly observed by any mechanism.

Now, it is expected that through BINGO, the scientists in charge of the project will be able to continue developing and advancing the study and understanding of dark matter through concrete measurements of the deep universe, which will open new opportunities in the fields of fundamental physics and cosmology.

For now, the total investment allocated by both nations for the implementation of this joint project is unknown; however, it is estimated that, for the moment, around 216,000 dollars, the equivalent of 1.2 million Brazilian reais have been invested for the first research phase.

The project is expected to begin operations in the Paraíba region of Brazil in the year 2026, and according to reports, the main equipment for the radio telescope will be transported to the Latin American country from the city of Tianjin, in China.

With the implementation of this joint project between Brazil and China, known as BINGO, it becomes evident that the People's Republic of China is interested in increasing its strategic, technological, and scientific presence in the Latin American region.

Moreover, with Brazil as one of the two leading actors in the management and execution of this scientific project, Latin America’s geostrategic position as a key player in the global space race is expected to be strengthened.

Likewise, it is expected that other outcomes of the BINGO project will include the transfer of scientific knowledge and technology, contributing to the training of local Brazilian talent, as well as revitalizing the communities located near the area where the infrastructure will be established.

Last but not least, once the BINGO scientific project is installed in Paraíba, Brazil, the infrastructure is expected to become a reference point for dark matter research on an international scale and position the Latin American region as a key player in science and space exploration.
