The largest two-dimensional map of the universe ever released, including 2 billion objects

1-14-21, National Astronomical Observatory Beijing-Arizona BASS survey team and the Dark Energy Spectral Survey DESI International Collaboration Project team jointly released the latest giant two-dimensional sky map of the universe. This is the largest cosmic sky map obtained by human measurement so far. 200 researchers from all over the world have spent 6 years on joint observation and data analysis, covering 20,000 square degrees of the sky, which is about half the area of the whole celestial sphere, accommodating 10 trillion digital pixels and containing 2 billion celestial objects.

China’s quantum communication network

China’s hack-proof quantum communication technology is “primarily ready” for practical use after a 4,600km (2,858 mile) network was put through two years of experimental service, researchers announced.
When fully developed, quantum communication can be applied in fields such as finance, defence, government administration and electronic information, according to scientists. This network consisted of the Micius satellite – the world’s first quantum communication satellite launched in 2016 – and more than 700 optical fibres covering 2,000km and connecting 32 nodes across four provinces and three municipalities in China. It was completed in 2017 and has realised communication up to a distance of 4,600km.

South Korean artificial sun sets world record, runs for 20 seconds at 100 million degrees

The Korea Superconducting Tokamak Advanced Research or KSTAR has taken a major leap forward in the development of a working nuclear fusion reactor. Unlocking the power of nuclear fusion has been the dream of scientists since the early 20th century but has proven a tough puzzle to crack. Nuclear fusion, which works by combining two atomic nuclei into a larger nucleus to release energy, promises to unleash more energy than it consumes.

Three-segment solid rocket booster

China’s first independently-developed 3.2-meter three-segment solid rocket motor for civil space completed its first ground test in Xi’an, Northwest China’s Shaanxi Province on Wednesday, marking China’s largest and the most powerful segment-type solid rocket engine tested to date. The segmental solid rocket buster is a solid fuel rocket engine divided into several sections and each section has its own shell, adiabatic structure and propellant charge column.
The engine can be applied to large & heavy rockets to meet the needs of space equipment, manned moon landing & space exploration.
