ScienceDaily (May 11, 2010) — A heavy runaway star rushing away from a nearby stellar nursery at more than 400 000 kilometers per hour, a speed that would get you to the Moon and back in two hours. The runaway is the most extreme case of a very massive star that has been kicked out of its home by a group of even heftier siblings.
This image of the 30 Doradus Nebula, a rambunctious stellar nursery, and the enlarged inset photo show a heavyweight star that may have been kicked out of its home by a pair of heftier siblings. In the inset image at right, an arrow points to the stellar runaway and a dashed arrow to its presumed direction of motion. The image was taken by the Wide Field and Planetary Camera 2 (WFPC2) aboard the NASA/ESA Hubble Space Telescope. The heavyweight star, called 30 Dor #016, is 90 times more massive than the Sun and is travelling at more than 400 000 kilometres an hour from its home. In the wider view of 30 Doradus, the homeless star, located on the outskirts of the nebula, is centred within a white box. The box shows Hubble’s field of view. The image was taken by the European Southern Observatory’s (ESO) Wide Field Imager at the MPG/ESO 2.2-metre telescope on La Silla, Chile. (Credit: NASA, ESA, C.

Tantalizing clues from three observatories, including the NASA/ESA Hubble Space Telescope's newly installed Cosmic Origins Spectrograph (COS), and some old-fashioned detective work, suggest that the star may have travelled about 375 light-years from its suspected home, a giant star cluster called R136.
The homeless star is on the outskirts of the 30 Doradus Nebula, a raucous stellar breeding ground in the nearby Large Magellanic Cloud. The finding bolsters evidence that the most massive stars in the local Universe reside in 30 Doradus, making it a unique laboratory for studying heavyweight stars. 30 Doradus, also called the Tarantula Nebula, is roughly 170 000 light-years from Earth. Nestled in the core of 30 Doradus, R136 contains several stars topping 100 solar masses each.
The observations offer insights into how massive star clusters behave.

In that picture it radiates blue, have i read something about the falling of a blue star somewhere? i have read so much info i can't keep track anymore.

Well to bad.
Let me start with a star and a flag.
Amazing isn't it

how stationary was the star before it began running? did it have a path that it followed? or did it just suddenly start moving?
it has always been my belief that with each star there is a related event within our realm of consciousness, could this have signaled an event within OUR realm of consciousness?

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.
"It is generally accepted, however, that R136 is young enough that the cluster's most massive stars have not yet exploded as supernovae," says COS team member Danny Lennon of the Space Telescope Science Institute. "This implies that the star must have been ejected through dynamical interaction."
Astronomers have been on the trail of this rogue star since 2006 when a team led by Ian Howarth of University College London, UK, spotted it with the Anglo-Australian Telescope at Siding Spring Observatory. The observation revealed that the stellar misfit is an exceptionally hot, massive blue-white star and relatively far from any cluster in which such stars are usually found.
Sifting through Hubble's archive of images, astronomers found another important piece of evidence. An optical image of the star taken by the Wide Field Planetary Camera 2 in 1995 revealed that it is at one end of an egg-shaped cavity. The cavity's glowing edges stretch behind the star and point in the direction of its home in 30 Doradus.
Its velocity corresponds to an unusual motion relative to the star's surroundings, evidence that it is a runaway star.
The wayward star will continue to streak across space, says team member Paul Crowther of the University of Sheffield in England, and will eventually end its life in a titanic supernova explosion, likely leaving behind a remnant black hole.
