A star has been spotted near the Milky Way's black hole, with reports indicating it is the fastest-known star in the area. The star's speed is described as being around 3% of the speed of light, or approximately 18 million mph, and it orbits the black hole in a relatively short period of time, possibly just four years. The discovery of this star may help test Einstein's theory of gravity, although the specifics of its orbit and the implications for scientific understanding are still being reported.
