The astronomy world is still in shock after a star 320 times the mass of our Sun was discovered
this week. A couple of days later, scientists, once again, found an incredible star that reached an astronomical speed.
According to Space
, the Hubble Space Telescope photographed a star shooting out of our Milky Way Galaxy at a speed of 1.6 million MPH (2.5 million KPH). The star’s speed is three times faster than our Sun’s orbital velocity.
Astronomers believe the star is part of a triple-star system that traveled through the Milky Way galaxy more than 100 million years ago but wandered too close to a black hole that captured one of the stars and ejected the other two, which then formed a super hot blue star.
“The star is traveling at an absurd velocity, twice as much as it needs to escape the galaxy’s gravitational field,” said Warren Brown of the Harvard-Smithsonian Center for Astrophysics, reports Wired News
. “There is no star that travels that quickly under normal circumstances — something exotic has to happen.”
According to a Hubble news release
, the star is named HE 0437-5439 and is traveling 200,000 light-years high above the whirling disk of the Milky Way.
