a binary pulsar in a 53-minute orbit detected by fast
fast, china's five-hundred-meter aperture spherical telescope has discovered a binary pulsar with an orbital period of 53.3 minutes, the shortest known period for a pulsar binary system so far. the discovery, published in nature on june 21, will help understand the evolutionary model of spider pulsar systems.
shiyan-25 space experiment satellite launched
china launched its shiyan-25 experiment satellite on june 20 to conduct mainly new earth observation technology experiments. the launch was the 477th flight mission conducted by the long march rocket series.
scandium superconductivity discovered
a new record for the highest transition temperature of elemental superconductivity was produced. scientists from two chinese universities have discovered that elemental scandium has a superconducting transition temperature of up to 36 degrees kelvin at high pressure. the results were published in physical review letters on june 22.
china's first high -pressure pure hydrogen pipeline tested
china successfully completed the first high -pressure pure hydrogen pipeline burst test on june 25, laying the foundation for large-scale, low -cost and long-distance pure hydrogen transportation.
