Mystery Star Speeding Through Milky Way at 3 Million MPH -A Galaxy Classic

Neutron_star_rx_j08224300_2 One of the the fastest-moving stars ever discovered in the Milky Way has challenged theories about why it's moving so fast.

The object is a piece of the Puppis A supernova remnant created when a massive star ended its life in a supernova explosion about 3,700 years ago, forming an incredibly dense object called a neutron star.

Puppis_labeled_200_2 Astronomers used five years of NASA's Chandra X-ray Observatory images to show that the rogue star, poetically dubbed RX J0822-4300 (shown in image moving from point A in 1999 to point B in 2005), is careening away from what's left of a star that exploded about 3,700 years ago. The neutron star is exiting the Milky Way at about 3 million mph (4.8 million kph). Other hypervelocity stars known to be exiting the Milky Way move at speeds about one-third as great - believed to be hurled toward interstellar space by an aggressive, supermassive black hole at our galaxy's center.

"Just after it was born, this neutron star got a one-way ticket out of the galaxy," said co-author Robert Petre, an astronomer at NASA's Goddard Space Flight Center in Greenbelt, Md. "Astronomers have seen other stars being flung out of the Milky Way, but few as fast as this."

In the case of RX J0822-4300, a tremendous lopsided supernova explosion launched the neutron star to its blinding speed. It has traveled 20 light-years thus far, and will take millions of years to escape the clutches of the Milky Way. Despite using advanced computer models to simulate how such a stellar rocket could form, astronomers have no concrete explanation.

A star "believed to be hurled toward interstellar space by an aggressive, supermassive black hole at our galaxy's center"?
"Hurled AWAY from a "Black Hole" - accordingly to the accepted gravity theory on the Hill, such a statement must be something of a contradictionary of terms!
- But of course such a phenomenon is quite normal for our galaxy if only you get the right perception: Everything in our Galaxy is "hurled away" from the very center of our Galaxy!
The traditional cosmologists have got it all wrong regarding the movement in our Galaxy. Observing the bar and the spiral closely in our Galaxy, the movement clearly goes from within and outwards, "hurling" everything out from the center, in which new Suns still are born - and NOT sucked in.
Furthermore: The very same story of such an outgoing creation in our Galaxy, have been told by our ancestors for thousands of years in their Mythological telling of Creation: Everything was once in the middle of the garden, Eden, but was moved "out of the center in the garden", The Milky Way center where the Tree of Life is standing.

Taht is: Our ancestors had a far better cosmological and holistic understanding of Cosmos than the modern science.

Wow...
I agree with Ivar...massive external black holes can suck a fast star outwards......
NOT the poor main black hole in sagittarius A.

OK it seems a mistery....1 of the many...

Regards to high speed stars...provided thy do not hit our solar system

It could be a slingshot effect.

The velosity of light as we know today in our science of few hundred years may well not be a constant on the cosmic scale of 14 Million years of ceration. Such wonders will continue to be observed in future as we have hardly covered the universe with our incomplete science. Mysteries like this will continue to provide scientists to remain numble and work towards better understanding without holding bias and keeping intellect wide open.

What % of the SOL is that? Also is it slowing down? due to the friction of the "Matmos" that surrounds us in Deep interstellar space. Plot its course and see if its going to eat anything in the near future (less than 40 years).
Prove Photons dont have mass.. even a tiny tiny amount..

The galaky just doesent make sense at all, it will continue to boggle the minds of us humans who cannot hope to get a grip on something so much larger and complex than our bodys and minds. I for one believe this so called star could be a ship.... sounds crazy ya but a star moving at 3 million mph now that just sounds odd its probably a ship controlled by sentient beings like us exploring the deep reaches of space I mean for all we know the images show a ball of light and its up to us to interpret what that ball of light is and i believe it could be either a star or a ship powered by dark matter lol!
