OT: Does this look like what happens if you shoot a bullet into a bag of fluid?

Depends on the bag of fluid and the bullet, but in general no. A plastic soda bottle full of water hit by a 55-grain Nosler ballistic-tip .22 bullet booking along at >3600 fps becomes a cloud of mist. A ripe tomato becomes red fog.

Size matters, or so they say.

That comet was supposed to be about the size of Earth, compared to the SUN.

So we need a slower smaller bullet or a much bigger back of water for the example.

The strange thing about it is that the ejecta shows before the hit... Always has.

Might depend on when you consider the "hit" to occur. The sun is spewing stuff out all the time, so that flow will bounce off the incoming object before actual "contact" is made.

Usually, when a bullet hit a bag of water, the bag of water isn't around afterward. Fortunately for us, that doesn't seem to have happened (this time...)

Right: "...a coronal mass ejection _coincidentally_ blasted out to the right just as the comet approaches ...". So, basically there's no point to the video. It's cool, but it might has well be PhotoShop, given it's a coincidence.

I ran across that yesterday, but can't recall which site. They dismissed it as coincidence right off and no explanation as why. My first thoughts where electrically charged solar system and the speed of gravity... Ran across this looking for that other site.

Like in this one the fifth paragraph they think it might show there is a bigger one behind. I don't see how the progenitor would be following.

I'm still stuck on why they named rocks on Mars after Scoobie Do.

Thing is, is that if we drop the ball and one or parts hit us we could be pushed back and forget again. Space exploration is great, but it will be for not if the command center is unplugged. At least if we make it back we might see our past attempt evident on the Moon and Mars.

Thanks for those links, SW.

I also went to SOHO's site itself.

Interesting stuff...

If you'd bothered to read the article you'd have gotten to the part where it says: "The video, captured by NASA's Solar & Heliospheric Observatory (SOHO), appears to show a fireball jet out following the collision. That's not quite what happened, NASA explained. Instead, a coronal mass ejection coincidentally blasted out to the right just as the comet approaches and is vaporized by the sun."

So, even though I don't have the latest whizbang flash-n-dash player, I can tell you that it can't possibly look anything like what it looked like when I shot the plastic jugs of water with my Lorcin .25.

Hope This Helps! Rich

The corona is plasma. It's about as dense as the neon in a neon tube or the mercury vapor in a fluorescent. or the argon plasma in a heliarc. wait - dome to think of it, the earth-bound plasma at atmospheric pressure is probabaly way denser, but then again, on the other hand, who knows the "atmospheric" pressure ("coronic?") of the lower layers of the Sun's corona? The Sun does have a much deeper gravity well than anything else in the neighborhood.

Cheers! Rich

I think it was on this site, which is really cool.

Even at those speeds, a comet is likely to be producing a significant amount of "atmosphere" use to melting, out gassing and the like, so it has something to "push against" and create a bow wave.

Yep, deeper gravity well, and higher surface temps.
