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

Posted on 01/19/2011 5:30:39 PM PST by ErnstStavroBlofeld

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.

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.

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.

We've got a small to average star. Put it next to a giant in comparison.

You bet. There are videos out there that depict the sized of stars compared to ours...The size of some of these stars are almost beyond comprehension.

Thanks for that.

Shot this image recently of M-13 star cluster.

M-13 is a Globular star cluster in the Constellation Hercules, which contains several hundred thousand stars. This system is approximately 25,000 light years from earth. Many of the stars in this image, are much larger than our own sun.

10"SCT-15x20s calibrated and combined in DSS. 6.3focal reducer, with LPfilters, Canon 40D @ISO800.

I’m a lifelong insomniac and I’ve found that wandering the universe is a great way to get to sleep.

Lately I’ve been thinking about conditions that would make life possible on a planet tidally locked to its sun. One I came up with that’s interesting to think about is a planet orbiting close to a red dwarf which in turn orbited a giant. If the stars were far enough apart you could get a planet with a stable orbit. The planet would have one side in perpetual sunlight and the opposite hemisphere would have a day/night cycle which would equal its year.

Obviously the variables are incalculable but its fun to think about.

every thousand years
this metal sphere
ten times the size of Jupiter
floats just a few yards past the earth
you climb on your roof
and take a swipe at it
with a single feather
hit it once every thousand years
`til you've worn it down
to the size of a pea
yeah I'd say that's a long time
but it's only half a blink
in the place you're gonna be

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.

So we're going about 150 miles per second. It doesn't feel like it.

I don’t worry too much about that, as I’m really confident life exists amongst the hundreds of billions of star systems throughout the universe. Even with our primitive technology, I think we’ve already discovered over 800 planets orbiting other stars, right in our own neighborhood. Given this fact, I would assume there are literally multiple trillions of planets where life might be possible.

The new worlds atlas on the site is pretty cool too. Kind of a 3-D map showing where the known exoplanets are in relation to us.

Not familiar with them, so those lyrics didn't get stuck in my head reading the earlier comments, like GP did.

It helps that I saw GP way back in the 1980s. In Boston, fwiw.

I don’t know...a simpler explanation would be an anti-matter ejection getting red-shifted to appear blue, rather than a 3 star trifecta merger ricochet shot out of a black hole.

Its a red hypergiant that’s 4900 light years away. I don’t have any estimates on when its expected to go boom. Its kind of an odd star.

Very interesting. I was reading about this ‘ejected’ star just recently. I’m just glad the thing didn’t come our way. It probably would have went through our Solar System like a hot knife through butter!

Likely the only scenario where we would have wished for something ‘little’ like a comet. lol
