During the late 1800's, researchers noted the similarities between comet behavior and electrical phenomena in mainstream magazines such as Nature, Scientific American and English Mechanic and World of Science. But in the early 1900's, astronomers backed away from those ideas because they imply electric currents between the comet and the sun, something 20th century astronomers were not willing to consider. They instead developed the "dirty snowball" theory of comets, which says that comet displays can be explained by ice and volatiles (compounds with low melting points) evaporating under the heat of the Sun.
Electricity, not heat, is at work on the surface of Wild 2. If this is true, then a second problem is solved. We don't have to wait for the rare impact to form the cratered landscape. The craters we see are being carved by electric arcs. These arcs also cause the (surprising) dark color of every comet we've seen up close. They produce the (surprising) x- rays that the ROSAT x-ray observatory discovered. And they create the (surprising) streams of rocky particles that pummeled the spacecraft, Stardust.
It is no longer important that comets be composed of mostly ice and volatiles. Electric arcs are strong enough to strip away rock. We use similar processes in industry here on Earth, both to remove material and to deposit it.
Plasma is any substance that contains charged particles: negatively charged electrons, positively charged ions, or dust particles that have an excess of either electrons or ions. Fluorescent and neon lights are plasma. Lightning is plasma. Earth’s magnetosphere, the solar wind, and the sun itself are plasma. The glowing nebulas in space, often called gas clouds by mistake, are plasma. So are the dark clouds, composed mostly of molecules of hydrogen, but revealing themselves to be plasma by their magnetic fields and radio emissions. Back on Earth, the familiar world dissolves in the realization that power lines are plasma; molten rock is plasma; even raindrops may be plasma.
One of the observations leading to the dirty snowball theory of comets was that most of the periodic comets begin to grow tails at about the same distance from the Sun: between Jupiter and Mars. The determining factor was thought to be the distance at which the comet became hot enough for water and other volatile substances to evaporate into space, creating the coma, or "head," and tail of the comet. But not every comet obeys even this tenuous "dirty snowball" criterion. Hale-Bopp in particular broke many of the rules. In the photo seen here, it is still too far from the sun for a "snowball" to melt, but it already displays seven jets. Four years after Hale-Bopp left the inner solar system, it was still active. It displayed a coma, a fan-shaped dust tail, and an ion tail -- even though it was farther from the Sun than Jupiter, Saturn or even Uranus. The comet's tail was shrinking, but it was still about five times longer than the distance between the Earth and the Moon. At this distance, the Sun's heat will not melt ice. If it could, the icy moons of Saturn and Jupiter would be as dry as our own scorched Moon. From an Electric Universe point of view, a comet's tail arises from the INTERACTION between the electric charge of the comet and the solar discharge plasma. The comet spends most of its time far from the Sun, where the plasma charge density is low. The comet moves slowly and its charge easily comes into balance with that region. On the other hand, as the comet approaches the Sun, the nucleus moves at a furious speed through regions of increasing charge density and varying electrical characteristics. The comet's surface charge and internal polarization, developed in deep space, responds to the new environment by forming cathode jets and a visible plasma sheath, or coma. The jets flare up and move over the nucleus irregularly, and the comet may shed and grow anew several tails. Or the comet may explode like an overstressed capacitor, breaking into separate fragments or simply giving up the ghost and disappearing. The dirty snowball model was never tenable and has been discredited. This has profound implications for theories of the origin of the solar system.
In the Electric Universe vision, these electrical behaviors explain straightforwardly the many phenomena that have appeared curious and enigmatic to space-age explorers: radio and x-ray emissions from planets and comets , polar jets of braided plasma filaments and hourglass-shaped nebulosities of stars (such as the Herbig-Haro objects imaged above), beams of energetic particles along the spin axes of galaxies, and everywhere glowing filaments and magnetic fields. The existence of plasma circuits underlies the contradiction between the isolated bodies of the gravity universe and the connected components of the Electric Universe.

Most of the voltage difference between the comet and the solar plasma is taken up in a double layer of charge, called a plasma sheath, that surrounds the comet. When the electrical stress is great enough, the sheath glows and appears as the typical comet coma and tail. Diffuse electrical discharges occur in the sheath and at the nucleus, radiating a variety of frequencies, including x-rays. The highest voltage differences occur at the comet nucleus and across the plasma sheath. So where the sheath is most compressed, in the sunward direction, the electric field is strong enough to accelerate charged particles to x-ray energies. That explains the crescent-shaped x-ray image in relation to the comet nucleus and the Sun. Flickering and occasional flare-ups are expected because plasma discharges behave in a non-linear manner.
We will be following with great interest the published spectra, light and X-ray curves and spectroscopic analysis of the ejecta from the impact. No one knows yet whether NASA will find the subsurface water that is required for the dirty snowball theory. Of course water in the coma is expected in the electric model due to negative oxygen from the nucleus exchanging charge with positive ions from the Sun. Most electrical theorists doubt the existence of extensive subsurface water. The bone-dry surface of Borrelly was a pretty good clue as to what may be most likely
"But as far as the Keck spectra are concerned, we still haven't identified what feature it is we were seeing. We did see it go away the next night. So, we are seeing a very short-lived 'something' that came about because of the impact. But I can't give you any more definitive answer of what it is, because WE haven't figured it out yet ..."

As far as top secret NASA anti-matter weaponry...
When the U.S. was developing Nuclear Weaponry during the cold war era, the scientists working on this project saw the potential for abuse that the U.S. alone becoming the only nuclear power, which is why at least five scientists, not working in tandem, but seperately, approached the U.S.S.R. and leaked our nuclear secrets to them (the most infamous being the Rosenburgs).
Do you really believe that the sceintists developing this technology, are so unethical and easily purchased, that they would make no mention of this in the media, or that other major powers in the world, China, Russia, England, France, Germany, etc. would make a big deal out of the fact that we are trying to develop weaponry more powerful than our sizeable nuclear arsonal?
While I do believe that the two flashes are interesting, and bear further scrutiny and analasys...
...the idea that some sort of new massive weaponry was used...
or that there are a bunch of space aliens hiding out inside the comet seem a little silly, and completely unfounded in any sort of science, pseudo or otherwise.

Take a good look at that picture. What you are seeing is the exhaust plume from an antimatter pulse unit.

Small pulse units ensure the comet will not be broken up into multiple impactors (like Shoemaker-Levy).
Why is it so hard for people to think of it like this... We have NEVER witnessed an impact of this magnitude in space. No one knew exactly what would happen. Something that was less than likely happened, such as the second burp from the comet.
We have to remember that, in a few months, the ESA will be launching a very similar mission that's aimed at an asteroid.
He has, however, pointed out that this explosion was much greater than had been expected (some scientists, before the hit, were openly wondering if it could even be detected).

So you have never seen the Shoemaker-Levy Comet impact on Jupiter?What shame, you really missed out on that one
You say no one knew exactly what would happen?
Of course not, but did you ever heared of predictions of what might happen and why that may happen? I think it's called hypothesis. Usually one makes such a prediction to see if ones theory about something is right or wrong.
So mr. cmdrkeenkid I must take it your an expert in matter-antimatter science or an expert in conspiracies. It must be why you state that the second burp was less than likely, because if you were an expert in space science you ought not have ruled out the possibility of two flashes. Even better you should have anticipated that possibility.
Maybe ESA and contractors want there own data?
Maybe it's scientific to duplicate an experiment?
Maybe ESA was just making sure, in case a wrong metric system was used by NASA?

Rosetta at a glance
ESA's Rosetta spacecraft will be the first to undertake the long-term exploration of a comet at close quarters. It comprises a large orbiter, which is designed to operate for a decade at large distances from the Sun, and a small lander. Each of these carries a large complement of scientific experiments designed to complete the most detailed study of a comet ever attempted.
After entering orbit around Comet 67P/Churyumov-Gerasimenko in 2014, the spacecraft will release a small lander onto the icy nucleus, then spend the next two years orbiting the comet as it heads towards the Sun. On the way to Comet Churyumov-Gerasimenko, Rosetta will receive gravity assists from Earth and Mars, and fly past main belt asteroids.
