This is the fastest star in the galaxy and moves at 1,200 kilometers per second

The universe is not a place that remains static. Everything moves, and also does it at great speed, as you can read in The speed at which all things around us (and ourselves) move.

Now, according to a study published in the journal Science by a team of astronomers led by Stephan Geier of the European Southern Observatory (ESO) in Garching (Germany), we know which star in our galaxy moves faster. And that speed is nothing less than 1,200 km / s.

This star is a compact and fast-rotating helium sphere called US 708. The team is confident that now that they understand the exotic past of the fast star, they will be able to learn more about its evolution, as well as get more details of the nature of type Ia supernovae, a subcategory of variable stars that occur after the violent explosion of a white dwarf.

To get an idea of ​​the enormous speed of this star, much higher than usual (a few hundred meters per second), I could travel from Earth to the Moon in five minutes. The reason for such speed is because the star was ejected from its system by the explosion of a supernova and, because it will escape the gravity of the galaxy and cross the intergalactic space without obstacles.
