Harvard - The Hubble Space Telescope has photographed one of the fastest stars ever recorded after the super hot blue star shot out of the Milky Way galaxy at 1.6 million mph (2.5 million kph) by a black hole.
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.
