Hypervelocity stars escape galaxies at high speeds
Hypervelocity stars are cosmic runaways, flung from their galaxies at over 1,000 kilometers per second, offering unique insights into galactic dynamics and black hole behavior.
Imagine stars moving so fast they break free from their home galaxies! These rare hypervelocity stars hurtle through space at over 1,000 kilometers per second, far exceeding the 550 km/s needed to escape the Milky Way. Scientists believe these cosmic runaways are flung out by close encounters with our galaxy's supermassive black hole, Sagittarius A*.
