Gravitational waves propagating at nanohertz frequencies?Do they exist?Yes.Four observational networks,from China,Australia,Europe-India,and USA,respectively,simultaneously answered on June 29,releasing results from their independent observations in the extremely low waveband of nanohertz.Consistent with each other,the results arrive at a common conclusion:our planet is immersed in a wavy spacetime ruffled by overlapping low-tone ripples.FAST,the Five-hundred-meter Aperture Spherical radio Telescope of China,is among the many giant telescopes that have played a key role in the search for this low-pitch voice.They are not the real detectors,though.

Scientists have sought to measure the magnetic fields of nebulae,which are believed to be the matrix of stars,in the hope of better understanding star formation,as the flux of magnetic fields across different parts of these“clouds”might give some clues about how stars are born.Decades of efforts have converged to build up a method called Zeeman measuring to reconstruct the magnetic strength from the observed spectrum.Unfortunately,accurate measuring is sparse due to the great difficulty in observation.

An international team of astronomers discovered delays in radio and optical fluxes from a black hole(BH)binary-about 8 and 17 days respectively-compared with the X-ray outburst from the same object.These delays,as explained by the authors,can be interpreted as evident formation of a magnetically arrested disk(MAD),a scenario predicted by a theoretical model that has long sought observational evidence for support.

The new Wide Field Survey Telescope(WFST),located on the summit of Saishiteng Mountain,Lenghu Town,Qinghai Province of China,officially went into operation on September 17th,and released its first-light image-a portrait of the Andromeda galaxy,an object 2.5 million light years away from the Earth.Capable of surveying the whole northern sky in just three days,the 2.5-meter-aperture WFST now ranks the largest optical time-domain survey facility in the northern hemisphere.

An international team of astronomers working with FAST,the Five-hundred-meter Aperture Spherical Telescope of China,reported on Oct 19 in Nature their discovery of an atomic-hydrogen cloud 20 times bigger than the Milky Way.This gaseous structure,the largest so far found by human beings,is located in the vicinity of Stephan’s Quintet,a compact group of galaxies;and might be associated with the violent interactions between galaxies during the Quintet’s early formation and evolution,said the team.

On the morning of October 9,the Advanced Space-based Solar Observatory(ASO-S),the first comprehensive satellite for solar dedicated observations of China,flew into its preset orbit from the country’s launching site in Jiuquan.Nicknamed Kuafu-1 after a mythological man well-known in Chinese culture for his persistent chase of the Sun,the 859 kg satellite will help scientists understand how some prominent solar activities happen and how they interplay with each other;meanwhile it will also provide support for warning and mid-to long-term forecasts of disastrous space weathers.
