Astronomers have discovered S301, the swiftest S-star in orbit around the Milky Way’s supermassive black hole, known as Sagittarius A*. This Sun-like star completes an orbit every 8.7 years and attains velocities exceeding 8% of the speed of light during its closest passage. Researchers indicate that its trajectory generates significant relativistic effects, including observable orbital precession, presenting a unique chance to evaluate Einstein’s general relativity theory in extreme scenarios. Upcoming observatories like the Giant Magellan Telescope are expected to yield even more accurate data, enhancing our comprehension of gravitational phenomena.

00:00A newly discovered star is racing around the Milky Way's central black hole at 8% of the speed of
00:05light.
00:06The star, called S301, orbits Sagittarius A, the supermassive black hole at our galaxy's center.
00:13It completes one orbit in just 8.7 years, the shortest known among all S stars.
00:19At its closest point, S301 reaches incredible speeds, creating extreme gravitational effects.
00:27Scientists say this gives them a rare chance to test Einstein's theory of general relativity.
00:32Its unusual orbit also helps researchers study how gravity behaves near a supermassive black hole.
00:38Although dust hides much of the galaxy's center today,
00:42future telescopes could reveal even more about this remarkable star and the mysteries of gravity.
