Scientists identify Milky Way's fastest star
A team of astronomers has discovered the fastest star in the Milky Way galaxy, called "S 301," which orbits at a speed of 25,000 kilometers per second around the supermassive black hole at the galaxy's center. This star follows an orbit extremely close to the black hole, completing a full orbit in just 8.7 years and coming within a distance no more than 12 times the distance between Earth and the Sun. This makes it the fastest known star in the galaxy to date. Over the next ten years, scientists hope to directly observe the black hole's rotational speed and test Einstein's theory using interferometry devices from the Very Large Telescope and the Gravity+ instrument. This discovery sheds light on the properties of spacetime around the black hole and enhances our understanding of the nature of matter and energy at the galaxy's core.
