Abstract: Among solar activities, flares and coronal mass ejections (CMEs) are the most powerful energy release in solar system and the main factors in the changes of space weather. Magnetic field reconnection has been believed to be the driver of these solar eruptive events. However,the solid evidence of the whole process are still missing. Now, the Solar Dynamics Observatory (SDO) finally captured complete evidence of magnetic reconnection in the corona. In this article,we briefly review the history of studies on solar eruptive envents, present the latest results, and discuss on the main research subjects in future.
