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 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.
