Star cluster thrown out of galaxy at speed of more than 2 million mph
Fox News ^ | April 30, 2014 | unattributed

Posted on 05/03/2014 9:30:01 AM PDT by SunkenCiv

Astronomers say they have discovered a star cluster that has been thrown in the direction of Earth at a speed of more than two million miles per hour.

The cluster, named HVGC-1, originated in the M87 galaxy and is expected to endlessly drift through space, rocketing through the voids between other galaxies.

"Astronomers have found runaway stars before, but this is the first time we've found a runaway star cluster," said Nelson Caldwell of the Harvard-Smithsonian Center for Astrophysics, who is the lead author on a study which is set to be published in the The Astrophysical Journal.

HVGC stands for hypervelocity globular cluster. These clusters are groupings of thousands of stars contained inside a ball a few dozen light-years across.

The team found HVGC-1 using the MMT Telescope in Arizona after spending years studying the space around M87. A computer then calculated the speed of the cluster.

"We didn't expect to find anything moving that fast," said Jay Strader of Michigan State University, who is a co-author of the study.

The Milky Way Galaxy holds around 150 globular clusters, while the M87 galaxy holds thousands, according to a news release from Harvard-Smithsonian Center for Astrophysics.

Astronomers believe HVGC-1 could have reached its current speed after passing through two supermassive black holes at the center of M87, which acted like a slingshot, flinging the cluster away.

well, if this guy’s coming right at us....

we may as well enjoy today (despite the crooks and enemy agents in WashDC)

since they gonna take over a smashed=up earth, anyway...
all they gonna wind up with is rubble, debris, and space dust

Its the weekend, ENJOY!

Maybe this is the quickest way to travel between galaxies. Just flung a star cluster out.

I’ve always had an avid interest in what goes on “out there”, and watch every offering on the subject on TV, as well-and I thought there was agreement that the speed limit in the universe was the speed of light, as per Einstein’s findings-have I missed something?

“a star cluster” ... “a dozen light years across” ... is heading for Earth ... and this broad cluster ... “is expected to endlessly drift through space” ... “rocketing.”

Doesn’t really sound like it will:

a) drift
b) endlessly

Given its speed of “more than two million miles per hour” and that it’s *not* “generally in the direction of earth” but *IN THE DIRECTION of earth.*

Given how broad the cluster is, it sounds like earth is pretty much in the path.

Given that, “endlessly” also does not sound likely?!

The artist's rendition can only be described as "fanciful".

The basis for this discovery is described in a paper, which is available in pdf format at this link.

Here's Figure 2 of the paper, showing an image of the object ( inset ) and the spectral classification according to the "uiK" system, analogous to "RGB" and other color systems. The blue and red objects are "high" and "low" velocity objects, and the diagram serves to justify the classification of this object as an HVGC.

Note that the velocity is of course measured along the line of sight, so it by no means implies that it's "coming right at us." Also note that the inset image is "archival", from the Canada France Hawaii Telescope .

You haven’t missed anything-2 million mph sounds crazy fast but it is only about 0.003 speed of light.

Nothing “passes through” any black hole. Light itself cannot escape one.

555.6 miles per second....near relativistic speeds .035c.

Should be interesting time effects relative to surrounding slower space objects.

From “After the Thin Man”:

Lichee Club Owner: Have you ever been thrown out of a place, Mr. Charles?

Nick Charles: Let’s see. How many was it up to yesterday, Mrs. Charles?

Nora Charles: Well, uh, how many places were you in, Mr. Charles?

HVGC-1: I got thrown out of a galaxy in M87. Now when I say I got thrown out of M87, I don’t mean they asked me to leave, and we walked to the edge of forever together, and I said, “Bye, everybody, I gotta go.” Six star bouncers hurled my cluster out of there like I was Frisbee (one of Earth’s leading intellects).......

oooops.....0.0029 light speed. Mars in 18 hours...Sol in 46 hours....the moon in 50 minutes...mild time dilation effects...communications would be interesting in terms of Doppler effects on frequency...it would have to be digital...analog would sound funny. If we could do ships that could reach 555m/ps the solar system would be doable...pluto in 1500 hours or 2 months. 20 to 30 days to Jupiter and Saturn depending on position....slingshot effects at 555mps could add 3 or 4 multiples of velocity to one’s craft....perhaps near 0.1c

nice. maybe NASA could send Obama and Biden to go tell them that its not nice in the 21st century for big space objects to go flying off at Utopia (Rock Three, Terra, Earth).
that we will maybe apply sanctions like freeze some bank accounts of some of the ETs’

The speed of light is roughly 166,282 miles per second.
Light travels 111,769,920 miles per minute.
Light travels 670,615,200 miles per hour.

So given the speed of light is 100s of times faster than 2 million miles per hour a star cluster reaching that speed is entirely possible.

Yep, slower than a slow boat to China in the big scheme of things. But they make it sound like it’s going to crash into us tomorrow. Makes for exciting headlines, but it’s too bad when the unexaggerated truth is interesting enough.

Well, we may know how fast and which direction it was headed when the light was produced, but how long did it take for the light (showing the cluster and it’s vector) to get here? Whatever we watch at a distance has already happened, it takes time for the view to arrive.

2m miles an hour is about 3 m feet per second or around 555 miles per second. SOL is about 186,000 miles per second. or about 670 million miles per hour.
