要在城市里看星空有点难,所以天文台要建在空旷、地势高的地方。乘坐地铁9号线到佘山站,多辆公交车都能将你送至佘山天文台。在这里,科研人员用天文望远镜观测星空动态,你能了解更多的天文知识。"近日,上海天文台一个研究团队在对超高红移类星体的调研中,重点研究了类星体CGRa BS J0906+6930,发现它是一颗距离我们遥远而且在射电波段明亮的耀变体,处在只有 To look at the stars in the city a bit difficult, so the observatory to be built in the open, high places. Take Metro Line 9 to Sheshan Station, and many buses can take you to Sheshan Observatory. Here, researchers observing the sky’s dynamics with an astronomical telescope can learn more about astronomy. Recently, a research team at the Shanghai Observatory focused on the research of the ultrashort redshift quasar by investigating the quasar CGRa BS J0906 + 6930 and found it to be a bright variant far away from us and in the radio band. Only in the
