Мы обнаружили самую быструю звезду, убегающую из Млечного Пути

The star J0927-6335 is traveling at approximately 2,285 kilometers per second—more than 8 million kilometers per hour. It exceeds the speed required to escape the Milky Way's gravitational pull and is already destined to leave our galaxy forever. In this video, we'll explore how the Gaia telescope detects such fast-moving objects, why normal stellar interactions can't accelerate them that fast, and how the supermassive black hole at the center of the Milky Way turns binary systems into gravitational catapults. We'll also recall the first hypervelocity star, HVS1, trace the path of S5-HVS1 from Sagittarius A*, and consider another acceleration mechanism associated with binary white dwarf explosions. We'll learn why some stars arrive from the Large Magellanic Cloud, whether entire planetary systems might escape with these fugitives, and how their motion helps us measure the invisible halo of dark matter. Finally, we'll see what happens to a star after its final exit into the intergalactic void and why the search for such objects is only just beginning.
