A team of astronomers, including University of Hawaii at Manoa astronomer Eugene Magnier, used the 10-metre Keck II and Pan-STARRS1 telescopes in Hawaii to find a star that breaks the galactic speed record. It travels at about 1,200 kilometres per second (about 2.7 million mph), a speed that will enable the star to escape from our Milky Way galaxy.
The star has another peculiar property in marked contrast to other hypervelocity stars: it is a rapidly rotating, compact helium star likely formed by interaction with a close companion.
Top and side views of the Milky Way Galaxy show the location of 4 of the new class of HVSs. The general directions from which the stars have come are shown by the colored bands.

What I really wonder about is, can it get out of the Milky Way?
Are there other examples of lone stars outside of the boundaries of any galaxy?
In 1997, the Hubble telescope discovered a large number of intergalactic stars in the Virgo cluster of galaxies. Later in the 1990s scientists discovered another group of intergalactic stars in the Fornax cluster of galaxies.
Recently astronomers have noticed a faint glow, that may be a product of intergalactic stars. This discovery suggests that nearly half of the entirety of stars in the universe may reside outside of the known galaxies.
Perhaps this star's path would get bent as it moves, eventually falling into the orbit at a further distance out from the center of the galaxy. Perhaps it would disintegrate at the unknown barrier that traps all matter within our galaxy.

Ha! surprise. Surprise.
See what happens when you set limits on what you think is possible/impossible?
