New Mineral Found In Meteorite 85
Virtucon writes "The new mineral was found embedded in the Allende meteorite, which fell to Earth in 1969. Since 2007, geologist Chi Ma of Caltech has been probing the meteorite with a scanning electron microscope, discovering nine new materials including panguite. 'Panguite’s primordial nature means that it was actually around before the Earth and other planets formed, meaning it can help scientists learn more about the conditions in the cloud of gas and dust that gave rise to our solar system.'"

How can one be sure a meteorite that fell on Earth in 1969 is representative for the "gas cloud and dust that gave rise to our solar system"? I mean, can't the meteorite be originated in other start systems?

Aside from the obvious unknowables at the moment, the interactions of the interstellar medium, interactions in transition from and into the systems themselves as well as the energy needed to eject the item from the system (which is also part of the transition out), we can do some basic math to calculate travel time, if we make a few basic assumptions.

You made an error in your calculation. Since 20 km/s is 1/15000 of the speed of light, it would take 15000*4=60000 years to travel 4 light years, which is quite a bit less than your number.

We can do some better calculations from those same numbers also.
For instance, 11km/s relative to Earth is below solar escape speed, so a rock moving that fast did NOT come from outside the solar system (barring some really interesting interactions with multiple planets on entry to the Solar System - and we can't assume that condition existed for most (or even many) of the meteors arriving at the low end of meteor speeds).
On the other hand, 25 km/s relative to Earth could be moving greater than solar escape speed, if it were moving more or less in the same direction Earth is at impact - if it's basically chasing Earth, then it's moving at about 31 km/s in excess of solar escape speed.
On the other hand, if it's coming in at a larger angle relative to Earth's motion, then it may still be moving at less than solar escape speed. Coming in perpendicular to Earth's orbital motion, for instance, leaves it moving about 4 km/s BELOW solar escape speed.
Which leave you with (assuming arbitrary of meteor orbits) less than half of all meteors coming in at the high-end of the speed range are interstellar, with an even small fraction of the slower ones being interstellar objects.
Which leaves you with most of them being local, with no regards to travel time.
Note, by the way, that travel time is pretty much irrelevant to the likelihood a rock came from around another star.
Note also that your travel time estimates are off by a several orders of magnitude. You have the approximate distance in meters to Alphacent correct, but you then divide that by a speed in km/s (giving you an error of 3 orders of magnitude), then you compound that error by assuming that the result of that first division was time in YEARS instead of SECONDS (giving you an error of another seven orders of magnitude).
The correct answer, by the by, for your numbers, is about 63000 years.

From the Wikipedia (I'd never taint my honor by RTFA):
"Panguite is in a class of refractory minerals that formed under the high temperatures and extremely varied pressures present in the early solar system, up to 4.5 billion years ago. This makes panguite one of the oldest minerals in the solar system. Zirconium is a key element in determining conditions prior to and during the solar system’s formation."
I'm no chemist, but from that it seems they know when it was formed because of the temperature/pressure required to join the elements together (now how they know how things were back then I don't know). But yeah, it's a pain when so-called journalists write but don't communicate much of anything.

Pb-Pb isochron regression for eight most radiogenic analyses yielded the date of 4566.2 ± 2.5 Ma. Internal residue-leachate isochrons for eight chondrule fractions yielded consistent dates with a weighted average of 4566.6 ± 1.0 Ma, our best estimate for an average age of Allende chondrule formation.

A titanium-bearing mineral has been accepted into the International Mineralogical Asoc.'s catalgoue. Chondrites are a class of meteorites, the important part being that they are supposed to have formed as such and were not part of a larger body. (No evidence of impact or melting).
Some carbonaceous meteorites have large (several mm diameter) grains of material which were formed in vacuum, in particular those of the CV subtype. This particular meteorite's chrondrules (that's what those grains are called) contain refractory (i.e. heat-resistant) material in the amoeboid (rounded, irregular shape) olvine inclusions. Olivine is a basic ( = low silica content) mineral series common in celestial bodies (also the inner earth) and very suceptible to weathering, that is, exposure to water. Altered olivine has been found in fragments of meteorites from mars, which is the reason it is believed that there once was a water on that planet. But that's another story.
