Hyperfast Star Was Booted from Milky Way
ScienceDaily ^ | 7/22/2010 | ScienceDaily

A hundred million years ago, a triple-star system was traveling through the bustling center of our Milky Way galaxy when it made a life-changing misstep. The trio wandered too close to the galaxy's giant black hole, which captured one of the stars and hurled the other two out of the Milky Way. Adding to the stellar game of musical chairs, the two outbound stars merged to form a super-hot, blue star.

This story may seem like science fiction, but astronomers using NASA's Hubble Space Telescope say it is the most likely scenario for a so-called hypervelocity star, known as HE 0437-5439, one of the fastest ever detected. It is blazing across space at a speed of 1.6 million miles (2.5 million kilometers) an hour, three times faster than our Sun's orbital velocity in the Milky Way. Hubble observations confirm that the stellar speedster hails from the Milky Way's core, settling some confusion over where it originally called home.

Most of the roughly 16 known hypervelocity stars, all discovered since 2005, are thought to be exiles from the heart of our galaxy. But this Hubble result is the first direct observation linking a high-flying star to a galactic center origin

I do not believe anything NASA says or prints anymore. They are known liars with no credibility.

There isn’t too much in space that isn’t cool in one way or another.

Did you think to ping Scooter with your opinions?

The interesting part of this is that this could not happen in a two-body system since center of mass momentum, and angular momentum have to be conserved, and requires a three body interaction.

I agree. More government funded “science” , just like the global warming hoax and the liberal mainstream media , all lies.

Here's a neat little gravity toy. You can plop down a make believe early solar system and watch the effects of gravity on the individual 'planets'. Occasionally a 'hypervelocity' body will be cast from central star.

That’s pretty cool demo of orbital mechanics.

Planetquest has a new toy that has a lot of potential. Its their planet makeover. Its not real detailed but you start with a certain size of planet and star and try to make them habitable.

Tweaker stars. Send in the galactic SWAT team.

Habitable for whom?
I mean unless you can create a environment for your genetically engineered and cyberneticly enhanced insectoid race...

Stars are extremely interesting.

I shot this image recently of the star Rigel.

Look closely to the upper right, close to Rigel, you'll see it's companion star about nine seconds of arc away. Rigel is a blue super-giant about 900 light years away.

Rigel is many times the size of our sun. Our sun would appear like a small dot compared to Rigel.

In fact, to put things in perspective, our sun would be about as large as Rigel's companion is to Rigel.
