Star’s extreme proximity to Sagittarius A* means it could open new window onto black hole’s fundamental properties Astronomers have detected the fastest known star in the Milky Way, hurtling around the supermassive black hole at the heart of the galaxy.

Since Brentford were promoted to the Premier League, United have lost two of four games at the Gtech, were outplayed in the one draw and, even in the game they won, were physically dominated for 45 minutes. However, their summer acquisitions have turned a team of uncommon weakness and slowness into one able to compete in duels, win headers and threaten in behind. That should mean United’s class tells in contests such as this – except no side is better at finding ways to lose matches they should win. Daniel Harris
