TL;DR: In this article, the fastest main-sequence hyper-velocity star (HVS) was discovered by the Southern Stellar Stream Spectroscopic Survey (S5), and the ejection trajectory and transit time of S5-HVS1 coincide with the orbital plane and age of the annular disc of young stars at the Galactic Centre.
