Brazil & China Partner to Build New Radio Telescope to Explore Dark Universe

Brazil and China have one of the most enduring partnerships in space science—almost forty years of jointly-built satellites, and now a radio telescope rising in the mountains of Brazil's northeast. Paulo Cabral reports from Paraíba and São Paulo. It will be the fourth largest radio telescope in the world and the first in Latin America. The main equipment for the radio telescope was transported to Brazil from the port city of Tianjin in China.

The Baryon Acoustic Oscillations from Integrated Neutral Gas Observations (BINGO) radio telescope is an international collaboration, led by Brazil and China, aiming to explore the Universe’s history through integrated post-reionization 21cm signals.

The dark universe is a significant area of research in astronomy involving dark matter and dark energy. Dark matter makes up about 25% of the universe's mass and is detectable only through its gravitational influence on visible matter. Dark energy, makes up about 70% of the universe's mass. It is a mysterious force that counteracts gravity and causes the universe's expansion to accelerate. Scientists are actively studying these two components to better understand the universe's structure and evolution.

A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy that studies the radio frequency portion of the electromagnetic spectrum, just as optical telescopes are used to make observations in the visible portion of the spectrum in conventional optical astronomy. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night.
