5.   But the Martian meteorites found on Earth show few signs of such damage.

6.   In months and years to come, the scientific community will continue to study the small Martian meteorite found in Antarctica, hoping for more definitive evidence of life.

7.   Last year a team of scientists reported that a Martian meteorite, found in Antarctica, appeared to contain ancient microfossil life-forms.

8.   Remember the Martian meteorite that captured so much attention last year because it may have contained traces of cells?

9.   Recent discoveries of Martian meteorites that have reached Earth have raised the possibility that bacterial spores could have hitched a ride on these rocks.

10.   Researchers from the University of Tennessee, the Massachusetts Institute of Technology and other institutions analyzed grains of minerals called pyroxenes from one Martian meteorite, the Shergotty.
