The Mystery X-Shaped Debris Trail:  NASA
A long time ago in a galaxy far, far away, it wasn’t uncommon to see X-shaped bodies dashing about a solar system. But in this era, in this neck of the universe, it is decidedly strange. Yet the Hubble Space Telescope picked up just such an X-shaped debris pattern trailing a tail of dust and gravel last month that has NASA’s brain trust excited: We may have witnessed two asteroids colliding head-on for the very first time.

The comet-like mystery object, 90 million miles from Earth, was first imaged up by the Lincoln Near-Earth Asteroid Research program in early January, at which point Hubble’s new Wide Field Camera 3 took over and captured the image here. But what looked at first glance like a comet proved in the Hubble images to be trailing a rough debris trail rather than the smooth dust envelope indicative of a comet. Ground-based telescopes also could not establish any of the gases usually present in a comet’s debris trail in the object’s spectra.

Instead, NASA researchers now think the debris trail was caused by the collision of two asteroids rather than the usual ice melting off a comet. With characteristic understatement, NASA described the collision as “energetic.” Perhaps a more appropriate word is “violent,” as the estimated impact speed of a collision of this nature is some 11,000 miles per hour, or five times the velocity of a rifle round.

However you want to describe it, if you look closely at the image above you can see that the nucleus of the debris is oddly outside the debris halo, indicating that some kind of smash-up did occur. Of course, there’s no way NASA can be absolutely sure of this. We have our own theory about what Hubble is tracking out there, and it’s from far, far beyond the Asteroid Belt.

Drr drr drr daa dAA berderda deee dAAA berderda diii daaa burderdedu, burr daa burdrdadii daa burderdadii daa berderdadoo, wa wa wa weeee wuuuu wa wa wa wee wuu wa wa we wu umm it got too hard lol.

Looks more like a Klingon D7 Battle Cruiser with a malfunctioning cloaking device. It's leaking kleptons or something. :)

I was going to mention that it like just like the space ship in the movie Life force.

Are you sure its not superman...

Looks like the war between humans and robots begins....The Cylons are coming!

As long as one doesnt collide with us I will be happy! LOL

This is tomorrow’s Physics. There seem to be a polarity pattern involved in the pulverization shown in the debris of this hypothetical collision.

Maybe, we might learn more from asteroid impacts with the LHC, someday!

Actually I believe NASA is wrong. This is the exit hole of a black hole spewing out crushed matter into deep space. A space rip expelling matter.

This looks more like the second stage of the mystery phenomenon spiral, the russians? are working on a system to control asteroids in outer space, ya think it's a coincidence, or their first try at hyper space. Also I heard tell the vehicle launched could fire up to ten nuclear warheads.

Something puzzles me here. In a collision in outer space, wouldn't all the debris from the collision radiate out in a roughly spherical pattern and just keep going? What forces would cause a trail to form behind the remnant of an asteroid? The tail of a comet is formed by solar wind, but I believe it is composed of gas, not rocks and debris from a physical collision.

A black hole going poo-poo?

It's worse. Could it be...YES! IT IS! THE BOORG HAVE CREATED ANOTHER SHIP OTHER THAN THE CUBE. I mean seriously this must be a scout. lolz -DaSonicMan

superdave has a point, since i first saw the picture I was trying to figure out what kinds of velocities from objects could result in this pattern. wait, while righting this I figured it out. there were to objects that collided, and each broke neatly in half and rolled over the other, this is why the "x" shape has kind of curved tips. in the picture one broke horizontally coming forward, and the other broke vertically moving away.

also the tail comes from inconsistent velocities. but the whole mass is probably moving in a general direction, which is why it is still a visible phenomenon.

if two large masses indeed collided, there should be large amounts of debris, also there should still be very large masses still intact. each of these masses have a gravitational pull, as well as a velocity in a certain direction. each should begin pulling the near by debris along with it. this should explain the "X" pattern as each of the masses, however many there may be are competing the "grab" the debris. this should explain the expanding cloud, and the widening tail. as this process moves on, there should be two to four distinct points that are pulling away from the cloud. also a large amount of the cloud should remain in place as the masses move apart, and this is the spot where they collided. also if there was a near miss, or some sort of gravitational anomaly (a series of aligned stars, or its passing by a black hole) that could also explain the cloud, but not explain distinct tails as it seems there are

a couple of points no one here seems to have considered....

1-- the debris pattern is also dependent on the number, size, physical structure, chemical/elemental make up, initial directions, velocities, and rotational speeds of ALL the bodies involved at impact (remember, kids, NASA only said it "appears" to be the after-effect of "two" asteroids colliding, but they may not know how many objects were ACTUALLY involved) and,

2-- while the impact is estimated to have occured approx. 90 million miles from Earth this is hardly deep space. In fact, it is about the same distance from us as we are from Sol. Therefore, the debris cloud is still subject to the effects of the solar wind.

These are just some of the factors affecting what we are now looking at.

Still.....pretty.

Two asteroids colliding, common. What is the possibility of that happening where we would actually see the aftermath. Also where is the remnants of the second astroid and it's path?

Wrong guys.

It isn't even a comet. It's the debris from a Romulan that is cloaked. These things happens all the time if the shuttle door is left open.

But seriously, we need a better watch system to keep track of these and if NASA cans the Mars missions, I suggest we try to get pieces of these comets (or Romulans.. whichever they are.)

Did anyone bother to ask the Democrats what they going to do
with the money already going to NASA? The money Bush had set aside for the moon mission & mars. They couldn't steal the torque funds by pasting health care. So they took it out on NASA. Every one needs to make sure not a single democrat ever sits in another office of government. Those BASTARDS.

It just dawned on me. The Democrats don't what us to reach Mars. They are afraid, that all of us will relocate their sorry butts there. Its better to teach pigs how to fly hear on earth than to explore space. And after looking at that picture in this article. I know what it is. It's all those turtles Iran launched in space the other day.

Oh where oh where is Richard Feynman when we need him? He'd have this sussed out in no time and have a smile and a punch line to boot! Man, I miss Feynman!

It is the ore vessel make a jump back to its home planet after picking up its load from the mining vessels on the far side of the moon.

wonder what ants think of us when they look up?

@ezap. They both have their uses. Republicans are here for me to make money when I (hopefully)become an engineer working for a military company. Democrats are here for... my.. good-will(lols) and my virtually non-existent income.

And of-coarse, the president is here to start shit abroad and at home so Rep. & Dem. have a job. Oh.. and protect the people's life, liberty, etc.

That being said.. This isn't an image from space, it's an image from an microscope observing the X chromosome colliding with a Y chromosome, and the X won.

Just in case some of the more attuned commenters are wrong and that thing isn't the Borg, the Romulans, the Klingons or Fox Mulder's sister coming home... why hasn't there been any follow-up images?

Even as mundane as a cosmic collision, there should be some revisiting the phenomenon to follow up the progress.

But to date, there have been none but the one.

Oh, they shut that part of NASA down.

why does it have to be a head on collision. why couldnt they be travelling in a similar direction and just butted up against eachother like cars trying to run another off the road. It would at least be a better explanation for that tail to me and they could still be going at enough speed to do some damage like knock a couple chunks off eachother to form an "X".

Weird weird weird the phenomena is a result of and asteroid breaking up by an unknown force thats all no crazy sci-fi crap please oh please crazies learn to taste reality.

I'm with Cyd, this is the a**hole of the universe, which not surprisingly is in our vicinity.

"If this interpretation is correct, two small and previously unknown asteroids recently collided, creating a shower of debris that is being swept back into a tail from the collision site by the pressure of sunlight, Jewitt said. They hypothesize that the filaments are made up of dust and gravel created by a high speed impact that could have occurred at 11,000 miles per hour. The orbit of P/2010 A2 is different from anything seen in Hubble images of normal comets, consistent with the action of a different process, said David Jewitt, an astronomer at the University of California Los Angeles, in a press release. The asteroid belt contains abundant evidence of ancient collisions that have shattered precursor bodies into fragments. An impact origin would also be consistent with the absence of gas in spectra recorded using ground-based telescopes. P/2010 A2 is different from anything seen in Hubble images of normal comets, consistent with the action of a different process," says Jewitt. Embedded in the filaments are co-moving blobs of dust that likely originated from tiny unseen parent bodies." Hubble shows the main nucleus of P/2010 A2 would be the surviving remnant of this so-called hypervelocity collision. Some are swept back by radiation pressure from sunlight to create straight dust streaks. "
Studeing asteroid collisions can teach us many things about the makeup of the universe.

Holly cow that is amazing photography! It would really be awesome to get a closer look if it were to happen, although I would of course not want to be too close to an asteroid collision! Keep up the great work...

What could have caused it to look like an X? Its really amazing and mysterious at the same time! Hope they could find out what that really was! Will www.cityvilledomination.org

I loved how NASA described the collision as “energetic.” Perhaps a more appropriate word is “violent,” as the estimated impact speed of a collision of this nature is some 11,000 miles per hour, or five times the velocity of a rifle round - Impressive and at the same time pretty scary!
