A hyperfast star if it leaves the galaxy
A hyperfast star if it leaves the galaxy
From the Harvard-Smithsonian Astrophysics Center in the United States, they have seen a star at a speed of 700 kilometers per second, twice the speed needed to leave the Milky Way. This star is the fastest observed so far. It has a name, but it is almost unreadable: SDSS J090745.0+024507.
It seems to have elements heavier than hydrogen and helium, like stars created in the center of the galaxy. According to experts, about eighty million years ago he left the center of the Milky Way and will need another so much to reach the end of the galaxy and go outside.
