Russian Meteor: Chelyabinsk Asteroid Had Violent Past

samzenpus posted about 2 months ago | from the use-your-words dept.

Space 24

astroengine (1577233) writes "The asteroid that hit Earth last year and exploded over Chelyabinsk, Russia, had a prior crash record. Fragments of the asteroid recovered after the powerful Feb. 15, 2013, airburst show it contained an unusual form of the mineral jadeite embedded in glassy structures known as shock veins. Shock veins typically form when the parent body of a meteor or asteroid collides with a larger object in space. Heat and pressure from the impact cause rock to melt. It later reforms bearing vein-shaped patterns. 'Impact-induced jadeite has been found from other shocked meteorites. However, a unique point of the Chelyabinsk jadeite is that it seems to have crystallized from melt. To my knowledge, previously reported jadeite in other meteorites is considered to have formed (by solid-state reaction) without melting,' graduate student Shin Ozawa, with Japan's Tohoku University, wrote in an email to Discovery News."

I used to play Asteroids. I wasn't very good at it.

I could make a quarter last so long that John (1979 Apu) had to throw me out of the 7-11 (1979 Kwik-E-Mart)

Yeah, but wasn't a quarter like $700 back then?

Slashdot's DRM bot has flagged your post as a violation of the DMCA. Don't EVAR post the last three words of that sentence again, or we will report you to the MPAA. SWAT teams WILL be mobilized.

And (just to be safe) don't even speak the last three words of that sentence, mkay?

(so far, you're safe to think those words, but we're working on that)

I don't study asteroids or meteorites for a living but the summary sounds like a whole lot of speculation to me. Perhaps there are lots of different ways the rock could melt and then reform.

Yes, just like on the road. If a car has dents and smashes, it is probably going to collect more and the next one may be from you!

If space had a 3 strikes law, perhaps this never would have happened. Now's the time to be tough on crime and pass some harsher laws! Think of the children!

Bruno -- assumptions? (0)

Anonymous Coward | about 2 months ago | (#47070657)

That is a whole lot of assumption. We can equally assume that a rock that large hurdling through space at phenomenal speeds towards and away from a massive star could probably be involved in some sort of plasma event. This type of event is why we see comets' tails. In plasma labs right now they are showing these types of markings are burns from plasma events. So... lets not settle this matter with a slash dot press release and what one graduate student from Japan said about his knowledge and his belief.... thanks. If you want more information on the sort of things I'm referencing watch a few of these http://youtube.com/suspicious0bservers

He grew up to fast on the hard turf of the andromeda galaxy. Kicked around for millennia earning the name "frosty piss" for his cool demeanor and ammonia composition. Before he was old enough to see a supernova he had already robbed a planet of its only moon and killed many fledgling comets on his rise up the ladder of astro crimes....

That space plane thing cut a precisely measured chunk off that asteroid that was passing near earth at the time, used some gravity control to tow it over here, and sent it into the atmosphere over Russia at a precise angle and speed that ensured it didn't impact the surface.

A weapon demonstration.

Thank you Astroengine! (-1)

At least you beat that bitch Phucking Phil Plait to the story. The douchebag (plucking phil dickhead plait) looks like a constipated grandmother. What a god damn cunt he is.

Doesn't really come as a surprise (1)

ildon (413912) | about 2 months ago | (#47071647)

This isn't really a surprise because an interstellar impact is probably what placed it into the path of our orbit to begin with. But hey, I'm no astronomer/astrophysicist/whatever.

A secret American weapon aimed at Mother Russia (1)

mi (197448) | about 2 months ago | (#47072101)

A fair number of Russians believe, the "asteroid" was, actually, an American weapon...

You can laugh at fellow American kooks, who suspect American government at everything, but the paranoia — against the same American government — is even wider spread over there.

Even earthquakes and tornadoes are firmly believed by some (or many?) to be triggered by the evil Pentagon or Gosdep (which is what "Department of State" translates as in Russian). I'd offer links, but they are all in Russian...

So in addition to Crimea... (1)

unixisc (2429386) | about 2 months ago | (#47085395)

...there could have been more territory the Russkies could have added. If only, instead of a diameter of 17 meters, it had been a diameter of 17 kilometers, and dropped along the Russo-Kazakh border, the Russkies could have had all of it, and annexed a bit of Kazakh territory to go w/ it, and Vlad could have had more land to show his people and keep his popularity in the 90%+

You see, this long history of crashes just proves that anything over seventy thousand years old should have its license revoked.
