Probing the origin and evolution of the Universe and all the matter therein has been theultimate goal of modern science. By “seeing” and “hearing” messages from the cosmos, astronomical studies have played essential roles. We now have entered a multi-messenger era that allows us to investigate various fundamental problems from different angles.   

 This workshop will be the last one in the framework of the LIA ORIGINS, which was established in 2009, January 1st under the agreement between China and France in the field of Astrophysics. To mark this 10th anniversary of the LIA ORIGINS, this workshop aims to gather together scientists, mainly from China and France, to present recent developments in different aspects, from the very early Universe to present Milky Way, and from cosmic structures to extrasolar planets. Opportunities and challenges from future large surveys and instruments will also be discussed.
