China: Socialist Light Shone on “Big Bang”! (26.1.2025)

Many experts at home and abroad said that the observation results of EP240315a by the EP satellite have deepened humanity’s understanding of early universe gamma-ray bursts, offer fresh insights into the origins and evolution of the universe, Xinhua reported.

The EP mission is one of a series of space science missions led by CAS. This is an international collaboration effort, featuring contributions from the European Space Agency (ESA), the Max Planck Institute for Extra-terrestrial Physics (MPE) in Germany, and the French space agency CNES.

Launched into space in January 2024, the satellite has achieved several initial discoveries, such as an uncommon transient phenomenon, advancing understanding of the universe and extreme physical phenomena, Xinhua reported.

China: Joint Research Team – Unexpected “Chirping Chorus” Detected from Outer Space! (23.1.2025)

According to the research team, electromagnetic bursts play a crucial role in the formation of the Earth’s radiation belts, pulsating auroras, and the precipitation of particles into its atmosphere. Traditional views hold that chorus waves are formed in the magnetic field of a dipole of near-Earth space, where the magnetic field is similar to a large bar magnet.

The newly-found chorus waves were detected in a region where Earth’s magnetic field is stretched out, which scientists didn’t expect. They lasted about 0.1 second with a frequency of nearly 100 hertz per second, which are similar to the waves detected in near-Earth space. That raises fresh questions about how these chirping waves form.

China: Chang’e 6 Samples Shed Light on Lunar Magnetism! (23.12.2024)

They discovered that the Moon’s magnetic field may have experienced a rebound around 2.8 billion years ago, suggesting that the Moon’s generator may have been reinforced after an early sharp decline.

“The reason for this rebound could be a change in the primary energy source of the generator or a restrengthening of the initial driving mechanism,” Cai said.

“The data fill in a billion-year gap in the evolution of the lunar paleomagnetic record and provide the first paleomagnetic measurements from the lunar far side,” a reviewer for the journal Nature said. “The authors are to be congratulated on a historic study that provides a major advance in our understanding of lunar magnetism.”

The evolution history of the Moon’s magnetic field is markedly different from that of the Earth’s, the research team said.

PRC: Lunar Samples Indicate Previous Magma Activity! (19.11.2024)

The study published on Science, conducted by a team led by Xu Yigang, an academician of the CAS and a researcher at the Guangzhou Institute of Geochemistry of the CAS, also confirmed magma activity on the lunar far side 2.8 billion years ago.

The study also indicates that the eruption of lunar mare basalt is influenced by the internal composition of the moon, explaining why the South Pole-Aitken Basin on the lunar far side lacks abundant volcanic activity.

“These samples are the first to be collected on the lunar far side so it provided a unique view to the moon’s global geological history. The results are novel and are deserving of publication in Science. They will be of interest to a broad readership,” Science reviewer Katherine Joy said.

China: Tian Guan [天关] “Einstein” Probe Detects Mysterious Celestial Object [EP240408a]! (1.11.2024)

In addition to detecting individual events, the EP has conducted repeated sky surveys, successfully generating China’s first all-sky X-ray map. Yuan said the satellite contributes data that represents over 30 percent of all information available on global platforms for the study of transient and eruptive phenomena.

The EP team annually solicits research proposals from Chinese scientists and provides data access to international researchers one year after acquisition.

China’s recorded interest in transient phenomena dates back to the Han Dynasty (202 BC-220 AD). In 1054, astronomers from the Song Dynasty (960-1279) documented the “Guest Star of Tian Guan,” later known as the Chinese Nova, a supernova explosion considered among the most significant astronomical observations in history.

Yuan said the Einstein Probe, known as Tian Guan in Chinese, honours this legacy and seeks to inspire future contributions to world astronomy.

China: 3-D Printer “Bricks” Developed for Future Moon-Base Construction! (21.10.2024)

According to China Central Television, the lunar bricks will be sent to China’s space station aboard the Tianzhou-8 cargo spacecraft to verify their mechanical and thermal performance, as well as their ability to withstand cosmic radiation. The first lunar brick is expected to return to Earth by the end of 2025.

China unveiled a national mid-term to long-term development program for space science on Tuesday, outlining a roadmap for the development of space science in China through 2050. The international lunar research station, which was initiated by China, will be constructed during the program’s second phase from 2028 to 2035.
