Hubble telescope has captured a heavy star from a nearby stellar nursery which is moving away at a speed of 4, 00,000 Km/h. This is the speed by which you can get to the moon and back in just 2 hours. This is an example of a massive star that has been pushed away from its home by its siblings.
These results came from observations of three observatories which includes newly installed Cosmic Origins Spectrograph of Hubble telescope. Currently the star have already travelled 375 light years from its home which is a giant star cluster named R136.
Currently that star is in outskirts of 30 Doradus Nebula which is also known as Tarantula Nebula. This is about 170000 light years from Earth.
According to Nolan Walborn (Space Scientist), these results are of great interest by scientific point of view as this is the first such observation in such region. Before this it was only in theory. Runaway stars can be made in a couple of ways. A star may encounter one or two heavier siblings in a massive, dense cluster and get booted out through a stellar game of pinball. Or, a star may get a "kick" from a supernova explosion in a binary system, with the more massive star exploding first.
