The Milky Way seems like a nice galaxy. Why would anyone – on Earth or any other planet want to leave the Milky Way permanently? That’s just one of the many questions to ponder as Chinese astronomers announced the discovery of 591 high-velocity stars and 43 of them appear to be heading out for parts unknown. Was it something we said in one of those SETI messages? “Though rare in the Milky Way, high-velocity stars, with unique kinematics, can provide deep insight into a wide range of Galactic science, from the central supermassive black hole to distant Galactic halo.” In a press release announcing the paper on this discovery published in The Astrophysical Journal Supplement Series, co-author Luo Youjun from the National Astronomical Observatories of Chinese Academy of Sciences (NAOC) explains the rarity of high-velocity stars – so-called because they’re moving faster than 65 km/s to 100 km/s relative to the average motion of the stars in the Sun’s neighborho ....

Now an exploration group, driven by astronomers from the National Astronomical Observatories of Chinese Academy of Sciences (NAOC), has found 591 high-velocity stars dependent on data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) and Gaia, and 43 of them can even escape from the Galaxy. Dr. Li Yinbi, lead author of the study, said, “The 591 high-velocity stars discovered this time doubled the total number previously discovered, bringing the current total number exceeding 1,000.” ....
