The year 2017 witnessed a lot of new discoveries and achievements. In this article, we list 9 top events, in two main categories:Research progress and development of astronomy instruments. The research progress ranges from the detection of neutron star merger to the discovery of habitable exoplanets and the strangest supernova explosion, as well as the most accurate cosmic-ray spectrum measured by China's DAMPE satellite and the first interstellar object, Oumuamua. The development of instruments includes the observation of Sgr A* by the event horizon telescope, successful launch of China's first X-ray satellite, HXMT, the grand finale of Cassini, and the news release from the FAST telescope. These new telescopes have been running well and we expect them to produce more interesting results in the years to come., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=9F3Ltw8nijI3R0WxswAhNQ==, pdfFileSize=4649226, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.

天文学是一门发现型的学科。2017年天文发现和研究进展目不暇接,一些新的大型观测设备开始运行。从研究进展和天文仪器2个方面遴选了9项具有代表性的天文发现和事件。盘点了引力波、系外行星、最奇特的反复爆发超新星、暗物质卫星公布首个物理结果和第一个系外天体"奥陌陌"发现等研究进展,在天文仪器方面包括了视界面望远镜进行黑洞成像观测、中国HXMT"慧眼"卫星成功发射、"卡西尼号"探测器毁落及中国FAST射电望远镜基本完成功能性调试。随着这些新设备的正常运行,期待2018年得到更多更有趣的发现结果。

Astronomy is a field full of discoveries. The year 2017 witnessed a lot of new discoveries and achievements. In this article, we list 9 top events, in two main categories:Research progress and development of astronomy instruments. The research progress ranges from the detection of neutron star merger to the discovery of habitable exoplanets and the strangest supernova explosion, as well as the most accurate cosmic-ray spectrum measured by China's DAMPE satellite and the first interstellar object, Oumuamua. The development of instruments includes the observation of Sgr A* by the event horizon telescope, successful launch of China's first X-ray satellite, HXMT, the grand finale of Cassini, and the news release from the FAST telescope. These new telescopes have been running well and we expect them to produce more interesting results in the years to come.
